Hi

I have a '96 carver 400 with the 'little' big blocks. Crusader 7.4 XLI

I think these are the original 96 manifolds. And I got a hole in one or the gasket is shot. I dont know because i took ownership in 2016. I purchased two Crusader manifolds and elbows, bolts, gaskets, etc. Its the one under the couch so it didn't get much attention.

I need some advice on the port engine, the elbows / manifold closest (And i mean close) to the fuel tank. I already soaked the elbow bolts and nuts with PB blaster and anticipate breaking the bolts. I already put a 9/16 wrench in them and doubled up with a 3/4 wrench. Would not budge. I didn't want to go too far and ruin something before the PB had time to set in. All the old parts are going to the recycler.

Here are my plans:

1) Remove the fuel computer and mount
2) Remove and hoses and drain antifreeze into a bucket
3) Remove the elbows and loosen the exhaust pipe and disconnect

The next part I really don't want to mess up with a broken bolt in the head.

4) Remove the exhaust manifold.

#4 - What do you do for extracting the manifold? At this point I just have 8 bolts to remove. I cant see down there. But I just spray the manifold bolts with PB.

Any other bits of advise? Maybe warm it up a little and break them loose with a breaker bar? On the fittings that screw into the manifold is there something I need to use, other than Teflon, to seal it?

Thanks,

Steven
