would anybody have an idea why my timing cover cracked. i didnt have any instructions for the set just kinda wingd it. im not really sur if the crank sprocket isn all the way on or whats going on but i could really use some advice.

 

Pictures would help and what specifically was installed.

 

The double roller that I installed I had to clearance my timing cover and oil pump. The shims that they supply make the oil pump stick out. I didn't feel comfortable clearancing it anymore so I took it off and threw on a Cloyes hex a just timing chain and gear set.

 

I had to clearance mine too. Not really a huge deal,

 

well i didnt think it was a big deal either till about an hour after i put the cover on it crackd the cover. im not really sure what happend it seemd like it had good clearance even after the shims.

 

I grinded mine down for a good hour and it still wasn't enough. I got pissed and took it off and got a single timing set. I'd say you already know why it cracked. You probably didn't have enough clearance when all the bolts were tightened, and the vibration caused it to crack or just the tightening of the bolts.

 

i see guess il be doing the same any advice on the best and strongest single

 

I haven't had a problem with my Cloye's

 

I put a Manley DB roller on and it came with spacers to clear the oil pump. I didn't have any clearance problems with the timing cover.

 

yea i used the spacers and all and seemd like it had clearance but then awhile after tightend it cracked

 

wait would an aftermarket oil pump be whats giving me the trouble. im using a melling pump.

 

I used a rollmaster double roller and a Tsp ported ls6 oil pump with no problems. I hear the melling pump is thicker and you have to do some grinding to get it to fit. Check out this thread https://ls1tech.com/forums/showthrea...hlight=melling

 

well it looks like im goin 2 be getting an ls6 oil pump instead

 

I have the melling also. The chain didnt clear the pump and the pump didn't clear the cover.

 

thanks for the help guys.

 

Did you swap the bolts in the front of the pump? Switch to a button head. That makes a world of difference. I had to grind, but not real bad.
