Okay well my 97 GT has 116000 miles on 'er. I've done a lot of just repair work and next is the engine. She's burnin oil and I'm almost positive it's the valve guide seals. When I had 5/30 oil in it, it would smoke like a banshee on hot startups and also after sitting at idle and when I first hit the gas. When I let 'er rip to redline, not a blurp of smoke, not a stumble, misfire, etc. Pulls hard for NPI but as is common for this head setup falls flat on it's face beyond 4800 rpm. I put in 10/40 oil with a pint of additive and the smoke has almost gone away, occasionally I'll still see a little bit after idling when it's fully warmed up though.
Did a compression test not too long ago and got about 150psi all around and this was on a cool engine. (can't compression test these hot as you probably know)
So I'm pretty sure my bottom end is fine. Question is this.. how long do the bottom ends last on these, N/A with light modification?
I was thinking of getting a PI motor but I'm not sure how much that would cost, because I've seen varying prices for low milage motors.
I am looking into doing a PI swap, complete intake and heads. I've thought about it and thought about it, and now that this car is not my daily driver, having 10:1 compression running premium would be worth the few bucks more a tank, on my weekend car. Also a blower is not an option at this point in my life and on this car, financially.
I was going to get a set of low milage heads and possibly a new intake, put in new seals (got um layin around), springs, and stage 1 N/A cams and put on a set of headers when they're back in the car.
I've seen kits for this swap that include the head bolts and all the gaskets required.
Any input let me know... I think doing a headswap may be a better choice for me right now on this car because the engine stays in the car and I spend less money and come out with a pretty good motor for my dollar.
