My car is burning oil really bad on a freshly rebuilt engine. I have narrowed it down to the number 4 cylinder after pulling the plugs. I'm assuming the problem is either a bad intake gasket or a bad valve seal. Is there a way to test for one or the other? I can get a leakdown tester from a friend but not until next week. Is there any other way I can test it this weekend?

 

When my intake gasket went I had vaccum in the crankcase. So, when I took the oil cap off I could hear and feel suction. Don't know if it'll help in your case but figured I'd post.

 

compression or leak test will work for a problem in the hole ,vacuum will test the intake

 

What do I want to look for vac wise with the intake? Something on the gauge or suction at the oil cap like recommended above?

 

I think you should see a steady fluctuating change in the guage if there is an intake leak. AKA the needle should jump around between two marks.

 

Ok well the weekend was too busy to work on it, but hopefully one night this week. I'm also picking up my friends leakdown tester today or tomorrow.
