my 93 13btt touring rx7 is fully stock no mods or upgrades and it has low power till u get to about 4000 rpms and the oil cap has the milky looking stuff on it when i take it off and it useing oil like i don't know what any test or diagnoses you guys think would help me get in the right dir. would help me out alot

 

A compression test will tell you if you most of what you need to know about the engine.

You also want to check into the oil consumption and especially if it puts out a lot of blue smoke on startup. That'd indicate bad oil control rings.

I think the milky stuff in the oil is a bad PCV system. I do not know how that functions in the FD. Perhaps someone can chime in with more info.

 

it does smoke when i first start it up but it the smoke is white and goes away in about 2mins after start up and thanks ill look into and let ya know how it goes

 

not sure on fd's but check afm and air leeks

 

white smoke sounds like coolant seal failure, search for doing a champagne test

 

Sounds like normal condensation burning off. Do a compression test and move on from there. Many people misdiagnose a bad engine.

 

Low power till 4000 RPM means that the primary turbo isn't spooling - or someone did a non-sequential conversion. Read the FAQ thread stickied in this forum for the turbo troubleshooting thread. Most likely it will be a solenoid.

The milky stuff in the oil cap is normal condensation as well. Tends to happen every change of season. You can use the Search button to search for past threads on the topic. Don't get paranoid and assume the worst. Inform yourself and learn and spend your money wisely. Start by reading the FAQ thread where we have compiled lots of knowledge.
