Who can i get a complete 3.1 rebuild kit from? Ive decided too rebuild my 3.1 while i save up everything i want for my ls1 swap. Need the car too be dependable till then so its for a rebuild. Also is it pretty straight forward rebuild on these engines?? any info on where too get the kit how much it cost and info on the rebuild would be appreciated.

 

Why rebuild then? Grab a JY engine and swap it out, or run the motor till it dies.

If you want a cheap re-fresh, go to Discount auto and order new bearings and rings, but it will still probably be less work/money to find a good running engine.

If you keep you fluids changed and tune-ups fresh, there is no reason you won't see over 200k miles on the stock motor.

I can't believe Scoggin-Dickey can sell new 2.8 fi long blocks for 87-89 firebirds for 800 bucks!!!

NO ONE SHOULD EVER REBUILD A 2.8 AGAIN!!!!!!!!!!!!!!!!!!!!!1

This really isn't bad, either...

Its already a good running engine only problem is a leaking rear main these v6 engines seems prone too that. I just want it too be 100% tip top shape as long as i gotta have it in there. I drive this car almost every day now i just dont need it braking lol and its one of those things that i have the money too do it right now so why not since a ls1 swap is probably half yr away for me at least for now i dont have time are everything i want for the car yet bc i only want too do it once lol. I was thinking bout 400 for the rebuild kit probably?

 

Parts are CHEAP. It's the machine work that kills the budget. I don't see how anyone can rebuild one for less than 900 bucks.

 

If the Cyl walls are good, and there is no damage to bearings, then it's cheap to re-fresh.

Sealed power bearings and rings are available at the local parts store for about a hunderd bucks (including FelPro gaskets). While you are at it, change the oil pump and inspect the cam and cam bearings for wear, and replace if necessary. Timing chain and gears are also cheap insurace at this point. Like Kris said, though, machining is the expensive part.

The hardest thing you have to deal with is either pulling the engine, tranny, or both. The two top bolts into the bell housing are hard to get to without detaching the trans and letting it fall back (might as well pull the trans at that point), pulling them out together, or cutting the firewall to get to them.

Rod and main bearings can be changed with the block in the car, but to get to that rear seal (it might be your cam seal, so change both) the engine and trans will have to seperated.

I have two 60*V6's apart right now, one with 120k miles, the other with 89k miles. The 89k mile engine (3.1) spun a rod bearing because of bad tuning with boost, the other is a 3.4 out of a running car. Both look like the honing was done yesterday, but you won't know until you have it torn down.

 

Ok sounds like im gonna just freshen it up a bit then. Ya getting it out of the car and the machine work wont be a problem I work at a classic car restoration shop i got access too any tool i could imagine including a machine shop. thanks for the tip on the cam seal ive neglected changing the rear for too long its always leaked a lil now its starting too pick up its time too get it done lol and ya i was going too change the oil pump also i have rocker noise on start up usually a good sign ur pumps bout too die thanks for the input.

 

Rebuild Kit: $295.66 (Northern Auto Parts) (minus cam, pistons)
Cam/Lifters: $127.92 (Delta Cam, 2.8 S10 Blazer towing cam, accidentally ordered lifters I didn't need though, cam alone was only $60-ish)
Machining: $225 (Hot tank block, install freeze plugs, install oil caps, install cam bearings, resurfance heads, valve job, polished/turned crank) (honing would have been another $35, but I bought a honer from the parts store and did it myself in about an hour)

Grand total: $648.58

Still need miscellaneous items, such as a new oil pressure sensor, new oil/filter, and a few tools(torque wrench, ring compressor).

 

forkvoid, that kit come with a crank?

 

Oh, no, it didn't. I knew there was something I forgot in my machining list! Polished crank. Adding that now.

I already had a junk 2.8 I pulled from my Firebird project(the whole car cost me $75). The local parts place wants $120 for a short block and $50 for a set of heads. So even if I had to buy everything, it would still be $820 for everything done.

 

The long block listed above is full of new parts; I just can't see that not being a super deal.

I rebuild stuff on the cheap, too, but especially where older 2.8 crank/block issues are concerned I just can't justify my time on the torque wrench with the old stuff.

This deal is especially good compared to reman engines offered from the auto parts stores...

 

Oh, definitely, the deal is quite nice. Part of the motivation for rebuilding a 2.8 rather than a new one such the one you linked is that my dad is helping me do the rebuild and explaining internal engine mechanics as we go. I learn so much better by doing than hearing/reading. (I had no idea what a crank, cam or lifters were about a month ago.)
