Exhaust manifold question

Hi all,

I am planning on removing my exhaust manifold in a few weeks for replacement.

I am tempted to give one of the exhaust manifold nuts an experimental turn just to see if it will budge at all easily.

My questions are:

Is there any reason why I shouldn't touch them until I am ready to do the entire job?

Will this affect the lock nuts? etc.

As always thanks in advance!

GHEN

I usually spray a little PB Blaster on them first. it shouldn't cause any problems for you to loosen then tighten back up. Know in advance though, sometimes the entire stud will come out with the nut. I usually get about 2 or 3 that do that. No big deal really. I have a friend who swears by the studs with the allen heads in them. That way you don't have anything in the way when you put the new manifold back on. They are polished and are only around $30 for the entire set. They make any future work a lot easier too.

Great minds think alike, I actually sprayed some PB blaster on them right before my post thinking "can't hurt".

Those are actually in the mail on their way to me already.

Thanks,

I don't know if your car is a turbo or not (or that it even matters) but when I disassembled the exhaust system on my car, two of the bolts wouldn't come apart due to rust over time. I ended up cutting the heads off with a small die grinder using a cutting wheel. It was not fun as there's was precious little room to work in.

Some people try to turn back their "odometers." Not me. I want people to know 'why' I look this way. I've traveled a long way and some of the roads weren't paved.

I'm in need of a stock collector for an 87 NA if you're getting rid of it....
