My specs are in my profile. I have been going through spark plugs of late due to a miss developing after about 15,000 miles on them. After changing them the problem always goes away. On the last change I notices that the rear cylinder, passenger side was wet and smelled like antifreeze. I looked all around the intake for a pool of leaking antifreeze but it was dry. I cranked the engine with no pugs and the cylinders were dry. My check engine light has been coming on and then would reset after a while then go on again. I can't remember the code generated but it had to do with the catalytic converter failing. I also have that annoying exhaust leak on the passenger side too due to the exhaust manifold leaking. I have also been losing antifreeze lately as well. There are no drips or signs anywhere. I thought it may be a leaking radiator. I decided to hook up my pressure tester and saw that the cap is rated to 20psi. I pumped it up to 15psi and noticed immediately that the pressure was dropping. There was no sign of a leak...The oil is clean with no signs of water contamination. Then to my horror I noticed that there was antifreeze coming from my exhaust! My immediate thought is a head gasket or intake manifold problem. I am not familiar with this modular engine. I am asking if anyone here knows of anything that might get me in the right direction to repair my engine. Is there an inherent problem with these motors? Should i try to find a replacement long block? I am not sure where to go with this... I am an experienced mechanic, but I work in the marine and diesel industry.
Thanks in advance...
