Hey folks I'm prepairing to tear down my 89 2.9l engine and had a question. I was looking around for a good rebuild kit and was just wondering if any of you had a good lead on a good kit.
I'm not looking to gain tons of hp, the truck has sat for three years, being started monthly ran at idle for about 30min. I know the gaskets can't be in great shape so i figured if I was gonna take it apart to put them in, I may as well do it right once.
I ended up getting the kit from rock auto gonna start this weekend. By the way with basic shipping I got the rebuild kit in a day( less then 24hours ) thats quicker then I could have gotten it from the local auto store/
Just out of wondering why in every post i have made, i have never really gotten an reply for anything. Thanks 99triger you are the only one that ever replied to me. My question now is am i asking the questions incorrectly? I'm still working on my 89b2 however being very reserved on using the forums, cause it would appear a waste of time.
UPDATE: heads (exhaust) looks like a mirror, lower intake and uppper intake port and polished. Just wondering how smooth I should get the intake on the heads, i'v heard mixed relsults about doing it on fuel injected engine some say leave it a little ruff for atomization and then some say smooth it out to a glass finish? I had the specs for the exhaust porting but am unsure of intake on the head. any ideas?

I really don't think its really a waste...
Jus' think of it as.. "Thinking outloud"
I personally like to see the progress your making... wether its in text on here or pics in your gallery.

I have a friend @ work that rebuilds some bigger V6/V8s (FI) and I always recall him mentioning that he leaves a slighty "rough" surface there.
But I'll bet he was working primarily on carbed engines, Rich.
The reason for leaving a rough surface on intake ports on a street engine is because it's thought that the fuel will condense on the port walls of a smooth surface at lower port velocity (RPM) and thereby loose the atomization of the fuel. The theory on FI engines however is that since the fuel is injected so close to the port that it doesn't really have time to "drop out" before it hits the cylinder. I don't know for sure, but I would suspect that that's more correct for engines that inject the fuel directly into the port just upstream of the valve. On most of the modern engines that we run, the injector is still mounted in the manifold, so the fuel/air mixture still has to travel through the port. I would tend to leave a slightly rough surface on the port walls and just polish the manifold runners as youi have done.
Are you using the stock heads, or have you upgraded to the WP heads? Also, did you see the 2.9 cam bearing poll in this forum?
