Tore apart everything on the engine to the block. Found out some sad @!*% and am going to either rebuild or engine swap now. The fact that it was raining all day was extremely fitting hahaha

Those wrap around the piston right? That's what I'm guessing is scratching the cylinder. I don't understand how that creates a knock however instead of a grinding. Also not sure how I would lose so much power when it is just one cylinder. Looks like I need to do more research in the matter, I'm way passed my engine knowledge

Well I tore apart the engine and I'm a little confused. Both heads are off and I looked at the valves, no light shown through when putting a flashlight up to it and they were all closed after loosening the rocker arms assembly. So it seems to me that they are not bent My cylinders all looked fine just had a build up of carbon on all but two, one thing however is grooves were on one of the cylinders indicating some form of wear. If I bent a piston rod however wouldn't the engine seized and not work? No cracked pistons, no light through valves, lifters seem fine and hold oil so what the he'll is causing the knock and terrible run? I'm about to just throw a new engine at this truck if I can get one for cheap that or look into long block short block

Installed some tube side rails I got from wreckers. I am surprised how beefy they are considering how much @!*% I hear about them over these forums hahaha

Maybe you should look into getting a D21 2WD so you don't have the excess body roll as well. Just a thought

That is not a bad idea I'll do that since it will be exposed anyways

Went to pick and pull and got to play around on a 91. Always fun

Just an update so yall dont thibk i abonded the ol' girl Well I went to pick and pull today to get the head assembly form a 91. Man yall didn't warn me that I would have to take off every damn thing! Haha I couldn't believe how much is attached just to get them off. I ran out of time getting the second head under the I take manifold so I'll be back tomorrow to get that along with a few other things like some nerf bars till I get rock sliders.

Damn I'm really hoping I get lucky with valves and lifters rather than having a bent rod. That much of a tear down is pretty much a rebuild. I'll perform a leak down test asap after buying the attachment. At least they are not *too expensive.

A little off topic I know but how do you like the xterras? I've always heard they were the rebirth of the pathy. That's exactly what I was thinking of doing and getting a lifter and rocker arms assembly while I'm at it off a truck if nothing else for extra parts. Awesome suggestion, i didnt even think of that. I'll have to pick up the attachment

Was able to get home early from work today and perform a compression test. All spark plugs excluding bank 2 and 4 were in perfect condition as expected with brand new plugs with only a total of 20 hours drive time on them max. 2 and 4 had huge carbon build up. Compression testing also showed each bank, again excluding 2 and 4 had 150psi. Bank 2 had 110 and when adding oil into it, it jumped up to 130 so I'm guessing a ring. Bank 4 had 80 psi, adding oil for the fun of it jumps barely 90 psi. Thinking bent valve which I was dreading. Going to try to go to junkers next time I am free and pull parts for replacement valve. If that doesn't fix my issue and it goes back to piston or cylinder then engine swap it is I'm thinking

I could see what looked like smoke forming for the fill plug in the video if I'm not mistaken. Standard OP compression is 100-130 correct? Saturday I'll give an update on where each cylinder is at

I'll share that nomination

Very true. Thank you for putting that into perspective for me.

Idle on my 92 is smooth, doesn't fluctuate like your xterra did in the video. Ticking yes though that's a given. I have not done anything to the truck yet, I work away from home so I won't be back to it till the weekend. Planning on doing a compression test before tearing anything apart

That is where you are losing me, if the lifters can't hold the oil pressure and collapsed then wouldn't that just need a new set of lifters and possibly (wear depending) rocker arms?

Any updates with this project?

Agreed haha

How so? I never had problems before I hydrolocked.

I agree with that. Better off getting a cleaner 2wd

I've never done it myself however it can be done. There are a LOT of people that slam down D21s down to the ground. If you don't get information here I would check into a low rider forum for the D21 hardbody. I ran across one awhile back but can't remember the name

Dang that is crazy! If you dont mind my asking, where do you live?

Those drawings are king

Hahahaha Savage xD

An old sock and 40% deet bug spray cleans up foggy head lights. Won't be a factory shine but in my experience it comes 80% more clear
