MTI is poop in my book.....just do not understand their mentality.

It may not be an issue, but I assume Cometic gaskets were used as recommended?

Trust me, nothing pisses me off more than someone trying to get something for nothing. If I caused the problem I would be the first one to admit it. I make mistakes. I don't expect someone to pay for MY mistakes. On the other hand I HATE paying for other peoples mistakes. I tried to resolve this (again) undercover. I saw it was going nowhere. I don't beg. I wasn't going to say anything, but I didn't think that would do any good to the next poor guy ready to drop 12k on a POS! If anyone can show me how I caused this problem. I would buy a brand new C5R block from them and I would tell everyone on this board that I don't know what I'm talking about. Thats a FACT!

Yes, they were. Even so how would that explain the sleeve being .003 higher that the block? And only on one sleeve.

So you are planning to deck the block and then go from there?

LASTLS1

iTrader: (7)

No, as **** as I am pulling the motor is not fun. I'm not going to have it done local as I first stated. I'm going to send it to Steve at Race Engine. I think he would be the best guy to look at it and repair it. I want it done right!!! It would be nice to get one full summer of driving the car. I only have 5k miles on the entire car. It needs to be driven!

U have helped me,I will never ever buy a wet sleeve or dry sleeve block
I will go LS2 or just build another stout 346....

C5R is out of the question for me,thats 6K......

If you are going to build a big motor, step up to the plate with a C5R block. You're just screwing around and wasting money on a sleeved block. Save up the cash, buy the C5R block, and sleep easy at night. Life is to short to just waste time and money having to redo things!!!!

Sounds like this is a Darton sleeving problem?

Anyone else sleeve blocks for LS1's?

No, I have done a little homework. Not to say none ever fail. If the sleeves are installed right, with the proper equiptment I think they would be fine. I have talked to people who have nothing to gain or lose by this. I was told that many Darton blocks are being used (WITHOUT) any problems! I am going to have the block repaired by Steve at Race engines in CA. I will let everyone know the results, good or bad. If I can make 10 motor passes without leaking coolant!!!!!*(^#&^@&*$%^$%6%$!#.. I really want spray the car but I'm scared. Other shops say not to worry about it, but after these problems? I really hope Steve can sort things out.

iTrader: (7)

I agree with you... But I was told the blocks were great, not to worry! Plus the fact that I have intended from the begining on spraying the car. I fully understand the risk involved. If I were to run motor only it would be C5R all the way. But at 6k a pop and the potential for nitrous problems, it seemed that the darton was the way to go. Looking back, I should have just went for the iron bolck. Saving the 100 lbs hasn't paid off, if you know what I mean.

You will be in good hands with Steve. Best of luck.

darton sleeves are not unlike any other aftermarket part. if properly installed with the correct machines and following the darton installation guide there are no problems and are superior to c5r blocks. blaming a darton sleeve in this situation is like me blaming a spring company because I installed them at the wrong height and rev'd them to 7k with a cam ill equiped and it broke

LASTLS1

iTrader: (7)

That what I hear also. At this point I'm going with the install as the problem. Other wise how are so many others running without any problems?

Gm runs a C5r,There is no way a Darton is better than a C5R or they would run one.
I wont believe it and no one will convince me,Put your Darton in a Lemans car and run it for 24Hrs and then tell me its as good.

C5R is the best.

Darton has stronger cylinder walls than a C5R. Fact, not speculation.

This is what happens when everyone tries to keep their problems hush hush so that the vendor will take care of them. It is a shame. I know of a few people who got burnt bad over sleeved motors from MTI and Morgan Motorsports. Hopefully people will search these posts and do their homework better before making the same mistake. The problem is more common that what you read...

I think the C5R is a great block. If the Darton works on motor. I will put it to the test on nitrous! I've been told it will hold up. We'll see. I will post all results.

Tell GM there C5R is not strong,they run it in the 24HR races..
Lets see Darton do it and then I'll believe its better
