Well it looks like it may be time to tear my engine apart. McMark was kind enough to point out my lack of compression this weekend. It looks like I have about 110 lbs on 2 cylinders, and 120 on the other 2. The motor has 64,000 miles on it (original), but it did sit for 17 years in a garage by the ocean. A guess is that the cylinder walls have pitted. I am thinking about rebuilding the top end. I realize there are some who disagree with ever taking this approach, but being that the engine has relatively low miles I hope it will work out. If I do choose this method, what would you all suggest in the way of cylinders/pistons sets, etc. I am running the orig Djet, so would going with the 96mm setup still function properly? I'm not trying to stray too far from stock (or to spend too much $$$), but wouldn't mind a little extra power. Thanks for any advice.

Done, done, done, and done. I spent the better part of the summer on the things you've mentioned and more. It's been on the road since late september or so. Not that it's running that poorly, it's just that I want it to run great. You're right though, I could probably continue driving for some time "as is"
Thanks once again Andy! The 96mm does seem to be the way to go. Do you know what the HP difference is??? I have a feeling my heads will be good. BTW, I took your advice and removed the brain and scraped out and de-rusted the "hell hole" As I suspected good metal under a little surface rust (IMG:http://www.914world.com/bbs2/html/emoticons/smilie_pokal.gif) . When I pull the engine for the top end job, I was planning on adressing the greater surface rust issue in the engine bay. Do you think por15 in there would look like bad? I was also thinking I would take out that fire mat stuff. I've heard it does little good anyway. And about that engine life... |
