Got 514 problems!

Here's the latest:

Finally found a shop that could do the job right.. there's nothing wrong with my engine!

I had initially taken it to Blood Enterprises in Auburn, WA but the result was:

1) Mr Blood could not get it tuned.. suspect he does not really know much about this issue and just wanted to rid himself of the dilemna

2) My windshield chrome trim has two nice scratches in it

3) Someone at Blood used my chrome front hoop bumper to pull on to move the car (a BIG no-no) and pulled the support tube out of the socket receiver. Fixing that today

4) Because he told me the engine was "hurt" I paid $240 to truck it to my buddy's shop where we discovered the problem was operator error at Blood

5) Paid Mr Blood way too much for very little result!

I finally took it to a really great local shop: Horsepower Connection in Olympia/Thurston County.

Brian is a great guy and very competent. He got it going with a complete reprogramming, reattaching the PCV valve and some adjustments and 3 hours on the dyno. Far less cost than Blood, to boot.
Must replace my hokey stock throttle cable bracket so I'll be going back there for a little final work when the part comes in, but I drove her home last night and she's running great with the EFI.. finally!!!

PS: Advice on an extra intake breather noted and if I have problems I will do this but during the full on dyno pulls there was zero oil emitted with the PCV properly attached. I suspect as the engine breaks in a gets a few K miles any potential existing problem will vanish

I also want to give a pat on the back to Cope Brothers engine shop in Tacoma, rebuilders of my engine. They did a superb job for a very reasonable price

Not knowing exactly what advice you're referring to, let me just clarify that my comment regarding the vacuum leak applies ONLY to carbureted engines. In your case, assuming you're using a speed density or alpha-n EFI system without a MAF...there is no problem letting air leak in to the vacuum side of the manifold as long as it's not so much that it creates an idle speed problem.

And, congratulations on getting it running well!

MAFS (Mass Air Flow Sensor?) included in the Holley package and thanks for the congrats.. it's raining today (this is the PNW!) but tommorrow she'll prowl the streets again!

I'm not clear on your response, but if your system has no mass air sensor measuring the air entering the engine, you don't have an issue with a potential PCV vac leak. The problem stems from allowing unmetered air to enter the PCV. Any unmetered air is air the processor doesn't know about...resulting in lean mixtures on mass-air systems.

To clarify, the problem was with "Blood Enterprises" in Auburn, WA , and not with the MAS or any other sensor or engine part...! It's operating fine now that a competent mechanic got his hands on the car!
