In Topic: Broken timing cover dizzy mount

Yesterday, 10:50 AM

 

Personally I would just lay the thing on its side, stick a 2X4 in the crank and be done with it, it's just an L16 block, I would never rebuild an L16 block, I would get an L20b as that would be the best bolt in upgrade you can make to a 521.

It won't hurt anything. The wood is a lot softer than anything in the crankcase.


In Topic: Header ?

Yesterday, 09:15 AM

The best header for that application is a custom built one. There are no good headers that you can currently buy.

 

A custom header (in stainless) will cost you about a grand so unless you're really trying to up the game, it's not worth it.


In Topic: L20B Exhaust Bolt Size and Lenght?

Yesterday, 09:12 AM

If you are talking about the bolts shared between the intake and exhaust manifolds, consider switching to studs. Two common problems with those bolts on an L series is that they break and also the threads in the soft aluminum head can strip quite easily. Studs will eliminate both problems. One added bonus to studs is that they help locate the gasket during install.

Pull oil pan, block crank with board, long breaker bar.

This is the best way to get it done. The board provides a positive stop for the crank without damaging anything when you wail on the breaker bar.

I would think the tiny 6mm bolt would strip or break before it built enough force to break off that much of the aluminum cover.

 

Seems like something else happened to cause this failure.

 

Would I JB weld it? Hell no. I'd remove it and replace it or TIG weld it. But to get you back on the road in the meantime? Ok, as long as it's not permanent.
