hey u13turbo, thanks for trying to help. i cant get acces to several bolt heads. the fuel injector tubes are in the way. i'll take pictures later if i cant get it off today... unless i just have to get at it from underneath? i'm gonna jack it up or try out my new ramps today and have a look...

by the way, i've come to the conclusion my Nissan TD27T manual is severely lacking. i also have the Haynes Pathfinder manual, but that doesnt help me a whole lot, especially inside the engine bay. what are you Terrano owners using? The only manual i could find for my truck was the TD27T manual. is there such thing as a Nissan Terrano service manual? I have the little Terrano manual for the glove box, but i'm not talking about that. i mean a big service manual like what Haynes makes for the Pathfinder. if anyone has a link, please post it, cause i cant find anything on-line.... thanks

well, i think i have to remove the fuel injection tube assembly. my manual doesnt have any directions for either of these tasks. can i just remove the injection tube assembly, or do i have to do anything first. i know i read about removing the fuel injectors themselves, and their was a process to it. i dont think i will have to remove the fuel injectors themselves this time, but i still dont know if there's any process to follow? also, there's 2 electrical connections on top of the intake manifold. i've figured out how to seperate them from one side, but the other side also has wires coming from it, and i cant seem to figure out how to disconnect it. i dont want to break anything. if anyone knows what i'm talking about, please chime in. i'll get pictures up tommorrow or sometime soon if i cant figure it out or i dont get any help. and speaking of that air/oil seperator tank i was talking about in my first post, i just ordered one off ebay. i was gonna just get a K&N crankcase vent filter, but it was $20, and i got this seperator tank for $35 with shipping. I also read those little filters arent actually street legal, and they get clogged fast. this seperator should work better, and be better for the environment. now i just have to see if i'll ever get it, seeing as how our postal service is on strike in canada right now... anyways, here it is: http://www.proautoluxury.com/img/items/GrayElephant/Done/RT-OCT-C-RD-1.gif

hi guys, i'm having some trouble removing the intake manifold from my '91 Terrano TD27T. I cant seem to find any info on removing the intake manifold from the Terrano. ehow.com has a discription about removing the Pathfinder intake manifold, but thats different from mine, so i'm gonna need Terrano owners to chime in i think. it seems like theres a bunch of stuff in the way. i cant access a lot of the bolt heads. it seems like maybe the cylinder head needs to be pulled or the fuel injectors at least. Just hoping to get some feedback cause i really dont want to have to remove more than i really need to. i'm new to tinkering with my engine, and i could be just missing something. i've been having some exhaust smoke problems. i've always had the black smoke, but recently i started seeing some blue. i had my mechanic look at my truck, at he said i should pull the intake manifold and give it a good clean to remove the carbon build up. he also recomend that if i were to un-connect my PCV hose that leads to my air filter housing, that recirculates exhaust fumes back through my intake, it would help. so i pulled it and lengthened the hose so it can hang down into my engine bay and vent into the atmosphere, and it made a major difference. i dont see any blue smoke anymore. and i dont have any black smoke while my engine is cold. but once it heats up, i start seeing black exhaust smoke again, probably from the built up residues and carbon in my intake manifold, and internals. once i clean it out, as long as i have this hose disconnected, it shouldnt build back up. i just need to place a filter on the end of it so as not to pollute. i'll get some pics up soon. for anyone having difficulties in this area, this is a great mod. my mechanic said i could also design a "seperator tank" so i can re-route the exhaust gases back into air filter housing and onto my intake after it seperates the oily residues and carbon it picks up along the way. but i think i'll just go with the filter option. K&N makes a nice little filter for the pcv hose on bikes that should fit perfect. my neighbour showed it to me. after i clean out my intake manifold, i think i'll try something like seafoam in my crankcase to see if it cleans anything internally. if i didnt have a diesel, i would try adding it direct to a vacuum line while the trucks running, but its very easy to hydrolock a diesel engine, and they dont recomend it, even though i've heard you can do it you go slowly. i dont want to risk it. so if anyone can help me get my intake manifold off, i would be eternally grateful. i'll try and get some pics up soon. thanks guys...

kiwipete- thats interesting about your TD27T... I was going to put in a 2-3" Body Lift to fit the 31's, but I'm wondering if maybe i should try fitting them without the body lift first? Do you know what size your stock wheels were? Cause unless they were 15x7 like the SE, they're probably 15x6.5 which arent supposed to fit 31's (although i know you can still use them if you wanted to). I havent had mine off to measure, and I cant find the specs anywhere. I'm going to order some 15x7 steelies with 3.75" back spacing and pick up some 31's. probably try fitting them before i bother with the body lift. keep all you TD27T owners posted...

well guys, after a few days of extensive internet searching, i do believe I've found out about the correct tire size for the 1991 Nissan Terrano R3M TD27T RHD Turbo Diesel. and they are 215SR15.... (about 28"x8.5"xR15) bummer. was really hoping they might have been the 31's.... I got P235x75xR15 on there now, which equal about 28.5"x9.25"xR15, and they fit great. It still looks like i have a lot of room, I'm thinking i will try putting 31's on the stock wheels. plan on doing everything right in about a year anyways, hopefully i wont mess up how the tire wears in that time. At least any future Turbo Diesel owners will know the stock tire size now.... EDIT- Heres the link for 1989-1992 Terrano R3M TD27T specs http://specs.cars-directory.net/nissan/terrano/2.7DT_R3m_16867.html

If anyone has used Toyo Open Country A/T 31"x10.5"xR15 tires on factory Nissan 15x6 wheels, I'd appreciate hearing your experience, and exactly what psi you ran the tires at. Thanks guys...

well, i just answered my own questions. I can see Nissan stickers on that bull bar, which have since fallen off. must be a factory extra... i want to get a bit beefier bumper for a winch anyways, when i can afford it... edit- went out to look at my wind shields, and yep, there's a faded nissan logo on one of them... 2 of them have also cracked. i have to take them off. gonna try sliding dental floss in between the wind sheild and truck door, and use "BG 244 injector cleaner" or "3M adhesive remover". I'll wait 'till summer for them to heat up real good, or maybe use a hair drier also. Thats what I read would work best anyways. If anyone has any experience removing that sort of thing, please chime in. i'll probably paint that little bull bar and the factory wheels black until i can afford steel wheels and a real bumper...

This is my truck. I didnt take this picture, I found it on the internet while i was searching for Nissan Terrano info. I know its my truck because of all the after market accessories, and the stickers (which I have since removed). Anyways, i've seen this exact bull bar and wind shields on several other Terrano's pic's, maybe its from Nissan...

Thanks for the help guys. From what I understand only the Terrano SE/Pathfinder SE came with 31's. I dont know what the R3M turbo diesel (TD27T engine) came with? I know you guys dont like answering redundant questions, but beleive me, I've been pouring over info all over the place, and I cant find the answers to these q's. So if any has any further info, I'd appreciate it. I also read 31's are supposed to go onto a minimum 15x7 wheel, and stock nissans (besides the SE) come with 15x6 wheels (I imagine the SE came with 15x7's for their 31" tire) but I read that 31's will fit onto the stock 15x6 wheel, and wear properly if i keep it down around 26psi. I read if i do this, it should fit on my stock Terrano without a lift or any trimming. Or maybe my turbo diesel came with 31's also? I really dont know. there is no sticker left on my truck. there does seem to be a lot of space with the 28.5's on there right now. I'll get some pics up when i get those 31's on. as is, its pretty much stock, I havent added anything myself yet. It came with a small bull bar, wind shield covers over the windows, fog lights (which have since broke), and a few interior after market electronics, but thats it. And since I've been looking at pics of the Terrano, I'm not even sure if the bull bar and wind shields are after market parts? It seems like alot of Terrano's have the exact same bull bar/wind shields I do. maybe they were a factory extra? I dont know, not all of them have it, but a lot do from the pics I've seen, just seems like a weird co-incidence. Dont get me wrong, I want to do a 2" susp lift and use 15x8 steel wheels, but I just cant afford a susp lift kit right now, and i really need new tires. I dont want to buy 28.5's just to replace them in a year or so when i do the lift. I'd like to fit the 31's on my stock 15x6 wheels until then, and hopefully i wont need to do any trimming, or at least minimal trimming. If anyone knows about fitting 31's onto a 1991 Nissan Terrano R3M turbo diesel (TD27T engine), without a lift, I'd appreciate it. And if anyone has any info regarding parts I'd appreciate that to. I would think most parts would be compatable with the Pathfinder also, but they do use different part #'s for different Pathfinder models, which leads me to believe they could be slightly different. and I cant return anything i order from the dealer. If anyone knows exactly which model this Terrano turbo diesel matches, I would greatly appreciate that info as well. Thanks again for all the help guys. I've been pouring over all the info regarding my issues, and I've learned alot along the way, and also learned a lot about other interesting topics that caught my attention. I did a lot of bookmarking! Josh

Hey guys, I'm in need of some help. I've been looking everywhere but cant seem to find the answer to my question. I have a right hand drive 1991 Nissan Terrano R3M TD27T (turbo diesel). I live in Canada, so the Terrano isnt in the computer at the Nissan dealer. Does anyone know which 1991 Pathfinder will match my Terrano for parts? The part #'s are different for Pathfinder SE/LE etc. and I'm not sure which model my Terrano matches up with. And either does the dealer. Can anyone help me with this? Also, I need a lock assembly for my front RH door, but since i have a right hand drive, and the lock assembly should control everything on the drivers side door, it wont fit on my right hand drive if i order a lock assembly for the drivers side door of a regular Pathfinder, and if I order a lock assembly for the RH door of a Pathfinder, it wont be able to control all the necessary components. See my problem? Does anyone know where I can order Terrano parts made for right hand drive vehicle's? Is there anyway to order original parts from Japan? Also, there isnt any sticker for tire size on my truck. It came with 28.5" tires, but it looks like I have a lot of room still. Does anyone know if I can fit 31"x10.5"xR15 tires on a stock 1991 Nissan Terrano R3M TD27T without trimming anything or cranking torsion bars, etc? Thanks for all your time, I appreciate any feedback, Josh
