I'll start by apologizing ahead of time to the people who will put their palm over their face and shake their head while reading this. Sorry! Also, sorry that this is a little long... I'll put a TLDR version at the bottom!
I've owned a completely stock '87 WE-4 for the last 13 years. It's a straight car with no rust, but it's got 172,000 miles. I've probably put 300 miles on it total, but that's because I was finishing my Ph.D, and I put buying a house before putting money into the Buick.
I'm finally settling down now, and I've got a little bit left over to start my Buick project! It decided to give me a reason to get started a couple of weeks ago when the bearing in the turbo decided to crap out. Instead of replacing it with a stock unit, I'd like to beef things up a bit.
A short list of what I'm thinking about include a TE-66, 60lb injectors, a double pumper, a 3200 stall converter, a 3" downpipe, a 4" intake, alky inject, and a chip. I'll probably pick up a new set of aftermarket headers since the driver's side is cracked anyway. Obviously, I'll brace it, etc. I'd like to target mid 10's to very low 11's, but I would still like it to be streetable.
So anyway, my question is this. Considering the high miles, should I rebuild the bottom end before going crazy? I know I need a new timing chain, and right now the engine rattles and sounds kind of loud above 3,500 RPM. I can't tell if the noise is coming from the valve train or deeper within, but I think its probably the lifters. There's no noise at idle, and the noise doesn't change whether it's warm or cold. It does not burn oil or smoke, and the compression test looks good. Of course it leaks oil like a sieve, and I'd like to get new seals either way.
The other question is... If I should rebuild it, should I attempt to do it myself? I've worked on cars for years, and I'm very mechanically inclined. I once pulled apart a '71 monte carlo but didn't finish it, because I bought the Buick and quickly lost interest in spending that kind of cash on an ugly old monte! I plan to do a ton of reading before working on it, but I have a huge underlying fear that I'll rebuild it, crank it, and blow a head gasket or worse.
So what's the verdict? Am I crazy for even considering doing it myself?
.......
TLDR version - 172k miles, good compression, doesn't burn oil but rattles at high RPM... should I rebuild the bottom end before really pushing the engine?
