Thread: small crack found-help

Tweet

Just got my engine back from assembly and there is 2 small cracks where the tranny attaches to the engine...I found them when i was going to put it on the stand? what does this mean?

It means that you didn't have the block magnafluxed when it was in the shop.

they said it was! I dont know how to post a pic, i can send it to your email?

I think what happened was when he took it off the engine stand that was the last bolt to come out and there was to much weight on it and it cracked, ill get the pics send in about 5 minutes.

the pics are to large to send, any other way?

there

how bad is it?

Im no expert, but a crack is never good and those dont look too healthy at all. I think Id be getting back in touch with him about it if he returned it to you like that. Just my 1½ cents worth.

If its only the one bellhousing bolt, I wouldn't do anything. Put that bolt in last, and don't overtighten it. Or leave it out altogether.

Ive heard of usin that to repair, Denny, does it really work as good as they say?

Kewl, thanks for the info Denny. So it works kinda like a concrete anchor and expands as you torque the bolt?

I had a similar situation with my BBC (stripped lower belhousing threads).Personally I've never liked using helicoils.They tend to pull out and are somewhat of a pain to install.If you can find them, I would suggest using E-Z lock thread inserts.

I've never had a Helicoil come out, and I've used them lots. Other guys say they have had problems, but I put that down to improper installation. Read the directions and you won't go wrong.

The helicoil isnt a bad idea. The cracks in the rear are far from any cooling jackets or cylinder bores. As a precaution, I would also apply a bit of JB weld across the cracks after the helicoil goes in. Sort of a second support

My expiriences are that even with properly installed helicoils, in continued use situations the lead thread sometimes unravels.Also with EZ locks there are no special installation tools or taps required.
