Default seafoam Idea or clogged cat?

If I put seafoam in slowly like put the hose in a for a second, take it out then put it in again, while holding the motor ar 4,000RPM or so wouldnt that not be enough to clog the cat? or am I risking it? I just spend over $100 on a cat including the install and dont want to do another one.

I sorta want to see how bad my exhaust manifolds are leaking or if it is just the mainfold gasket.

Any other ideas to introduce steam into the exhaust safely?

the whole idea of seafoam is that you let it sit in the motor for 15+ minutes to eat away at the carbon.

if you want to check for exhaust leaks throw some ATF in there.

Hang in guys.

Hans..your year (92-95 actually) is known for exhaust manifold cracks. You realize you have these cracks. Are you simply looking to make them worse before fixing them?

If so ...I will pm you a better method that I will not mention here.
