I had oil consumption issues also. Changed out the intake gaskets with SCE 1/8" thick gaskets and used Permatex Hylomar on both sides of the gaskets first problem solved. Checked the plugs and had one oil fould. Replaced the valve seals and now it is tan like the others. Try the simple fixes first before tearing the engine apart to replace rings.

Default Oily Smoke

I was reading your issues and my jaw dropped. I recently had a new cam installed on my 522 lumpy cam motor. I had never had smoke coming out of the pipes.

I went onto an on ramp the day I picked it up and notices ONLY from the passenger side that I got quite a bit of bluish smoke. Only on the passenger side though.

Took it back to the engine builder and we pulled the plugs. Center two plugs were wet with oil. Outside plugs were fine.

Did a compression test on all cylindefrs. They were 195-205 all the way around.

My builder had changed oils from 10-40 to 20-50.

This is too similar.....Anyone got any ideas???

Thanks,

Mike

Most of the time oil consumption on a new motor is caused by a leaking intake manifold gasket or damaged oil seals when they installed the springs. I replaced the intake manifold 3 times using different types of gaskets until it stopped leaking. I used a plain SCE gasket with the hylomar sealer that was made for use on Rolls Royce aircraft engines.. The stuff is great, but no one has ever herd of it. I won't use anything else. I even used it on my valve cover gaskets. You can take them off anf put them back without additional sealer. I tried Nitro seal, printo seal and Victor Reinz they all leaked! The gaskets were hard as bricks with very little compression. The SCE gaskets were softer and would compress a little better making a tighter seal. The only thing I had to do was trim them to fit the intake ports.
