Exhaust manifold problems
Hey guys a few weeks ago my exhaust got really loud and upon further inspection I found I had a cracked exhaust manifold. It is the two piece style so it is a little rarer than the one piece style but evidently it happens. Sa as a result I decided to be a little cheap (wait this become important later) and ordered a pair of used exhaust manifolds from Daveys Jeep Parts. I also sourced a Felpro gasket locally. Last weekend I tore it down removed the cracked manifold swapped over my O2 sensors, installed new gasket buttoned it all up, decided to start it to check my work, and WTF!!! I had a huge exhaust leak between the head and manifold, so I tried re-torquing every bolt, screwing around, etc, nothing worked. So on day 2 I took it all apart again, cleaned every surface: intake, exhaust and head so they were spotless, installed new gasket, retorqued every bolt with a torque wrench, buttoned it all back up, started it and ..... you guessed it huge exhaust leak between the head and manifold. So this leads me to my current train of thought:
I had a cracked exhaust manifold thats what was wrong originally. I replaced nothing else besides the manifolds and gaskets, the only thing I can come up with is the manifold is not making a good seal because the junk yard manifold is warped. Its all I can come up with, I mean has anyone else ever run into anything like this, I really think my cheapness has screwed me this time. I guess there is a reason most people don't buy used manifolds.
So I ordered two NEW manifolds that will be here by the weekend, so round three and I got a new Victor Rentz metal manifold gasket on the way,
Any comments, advise, criticism, suggestions, or experiences appreciated,
Will work for Jeep parts...
