  1. Ok. So here is an update of what went down so far on this project. We took the heads to my friend's dad's machine shop. We had to make jig so that we could mount the heads on the milling machine. As you can see, we first drilled out each hole then tapped themnto accept helicoil inserts. The one where someone had tried to drill out the stud and the drill walked into the head we had to drill and insert a 10 mm helicoil into and I found a 10mm - 8mm stud at the local Coastal Farm and Ranch store. As the hole wasn't quite on center, I had to grind out the hole on the headers so everything fit. Now it's all back together with a new water pump, timing belt, head gaskets, fuel injector cushions (purchased at my local Nissian dealer as I couldn't find them anywhere else and they only cost $14.00 for 6 of them), a K and N air filter element and I installed a transmission cooler. I had a little bit of trouble getting the timing right as the picture in the 1994 Service manual didn't match up but with a bit of trial and error me and a friend were able to get it running smoothly. I am veey happy that a now have a set of Pacesetter headers on my Pathy! and I forgot to mention I also put in a new fuel filter while I was at it. Next up is to change the tranny fluid out and install a new filter and new pada on the back brakes and I should be good to go fir another 50,000 until it's time fornanother timing belt and water cooler. [emoji3] I loved how easy it was to work on this car. Maybe all automotive engineers should be schooled in Japan! [emoji6]
  2. Yes, I did download a copy of the 1994 FSM. It was one of the firdt things that I did!
  3. First off I'd like to thank everyone for all of the advice that they have given me. I found out today from my friend who has been helping me that his dad has offered to let us use his machine shop and some of his time to repair these heads. I all ready purchased the gasket kit which includes the valve seats so it looks like a complete rebuild and repair of the heads. The water pump was leaking so that and the timing belt are being replaced along with the spark plugs. I also plan to change ALL the fluids, rear end, transfer case etc, flush and refill the tranny and then do a Sea Foam clean on the engine and did I mention that I also need to put in new radiator and while I'm at it I plan to install a tranny cooler as well. Then off to the Russian guy to get a $39,99 front end alignment. Whew. One hopes that the truck will last quite some time after this! Thanks to everyone and I'll post pics of the finished product!
  4. Well I just found out that my friend who's been helping me on this project got OK from his dad to use his machine shop to repair the heads. So thanks for all the sdvice and I'll let everyone know how this all works out.
  5. Ok. I was going to go with replacing the heads. My question is what tools does one need to ensure that the replacement heads are ok?
  6. Well the drilled out hole is about a 1/2 inch deep. Best i could tell by inserting a small phillips head screw driver in there and marking it.
  7. Ok. So I went and relooked at my heads. This is what I found. On the drivers side on the top hole, it looks like someone tried to drill out the droken stud and drilled a hole off-center. The hole on the bottom still has the broken off stud in it On the passenger side, it looks like the studs were drilled out and the holes are about an 1/2 inch deep and I can insert an 8mm stud in them but it's loose and wobbles. So I know enough that I wont be able to fix the off center drilled holenwith the head still in the truck and I quess my options are: 1. Remove the broken stud and replace it on the drivers side and call it good. I'll still have 1 stud missing and may suffer an exhaust leak due to this. 2. Take the head to a machine shop and have it fixed. Lord knows I can't really afford to do this. 3. Replace the heads. The Pathdinder I got the headers from.last weekend is still sitting in the junk.yard with food studs all the way around. I already bought a head gasket kit and all the tools needed. What would you do?
  8. So I guess I have one question left which is this: What is the maximum depth to which I can safely drill these holes? Is it 1/2 inch, 5/8th or what? I can then get or improvise a depth gage/stop so I then don't drill too deep.
  9. Thank you. I'll get a set of calipers snd donthe measurement.
  10. That's some good advice. I'll definitely do a few trials to get the hang of it. And I need to look at the holes in a new unit of time to determine the best course of action.
  11. I don't think that he drilled in to far as there are no leaks. I am thinking of using size 10 studs and buying the appropriate Helicoil set for that. How deep should I drill to properly set the Helicoil?
  12. I bought a 93 Pathfinder a few months ago. I noticed that the exhaust manifold leaked so I took it back to the place where I bought it and he had his mechanic "fix" it. Needless to say his repair didn't last long. I decided to do so myself. So I'm mid installing a set of Pace-Setter headers that I got out of the junk yard for $50.00. Today I took the stock manifolds off and low and behold, there was good news and bad news. The good news is that 8 of the 12 studs are all brand new! The bad news is that 4 of the holes are completely trashed. It looks like he may have tried to drill out the broken studs but that's all he did. On the drivers side the first two studs towards the front of the engine are missing and there is no threads left. The same on the passenger side but these are the two towards the back of the engine. At least the holes are in an easy to reach position. My question is, can I drill through these holes or is there something important like a water jacket behind them or can I install Helicoils in a "blind" hole here?
  13. The repeat posts happened because when I went to post the first time I got an error message that told me to retry so I did. A bunch of times. And yes, I will take photo's of the and get VIN # as well.
  14. I didn't look at the headers that closely to find out what brand they are. My Pathy is dark greenish blue and the one the headers are on is gold. I guess I better buy some good quality drill bits and stud extractors!
