I have read the procedure on rod bearings and it doesnt sound hard, its getting to them that sounds hard. I would need some major help with that part.

I really almost want to pull my engine just because I have never done it before, but I don't have the tools.. I love finding new things to clean.

If you dont have tools and experience doing this kind of thing. I would recommend you pay someone to rebuild your engine. Which will be $$$$$.

Internals is just not something I have experience with. At somepoint I might do rod bearings myself, but even that sounds scary to me. I am comfortable with changing the turbo and things like that.

If I were going to pay for a rebuild what are the bare bones neccesities, nothing fancy. I only have 3k to spend.

Replacing the oil pan gasket and rod bearings was the first project I did on my car. It took me about a month wrenching after work and on a couple of the weekend before I had it back on the road. It's not a complicated job, just long.

BTW, the car had 190k on it and the bearings that came were original and looked almost identical to the new ones going in. So unless you have a good reason to do it, I'd say don't bother.

Swap an NA engine and build your 951 engine the way you want!



Crazy talk!

If you haven't done that much wrenching on your car, pulling the oil pan on a 944 turbo is probably not a good place to start. Unless you know the car had spent time on the track and/or are unsure of oil change history, I don't think you need to worry too much about the conrod bearings. The oil analysis is a good idea though - if they see certain metals (i.e. copper) in the oil sample it's a good indication that bearings are excessively worn. If you decide to pull the motor out for whatever reason, sure, pull the head, inspect cylinder dimensions/condition, replace rings, maybe put on a Lindsay higher air flow head, etc. Even with the chip, no need to replace valve guides unless excessively worn though.
