Oil in throtle body normal? 200 89

posted by  someone claiming to be Haroon on  Mon Feb 26 06:49 CST 2001 [RELATED]

This weekend I took out the throtle body to clean it (170k). It was all gunked up very badly and sticking. Even though the 'volvo dealer' charged me $60 to clean it 10K miles ago. I don't think it was ever cleaned. The gunk was about 1/8 think in some places. I got it all cleaned out and it's nice and shinny now.

Oh and major tip for any one who wants to clean one. DO not remove the TPS senor. And if you do MARK the screw positions. It's a bitch to reposition it. Also remove the throtle linkage with the body. Do not disconnect it. You will not need to do any readjusting.

Anyway the question, I drove the car about 500 miles, some what aggressive highway driving (NJ) and inspected the throtle.

It's coated an oil layer. Is that normal?? (just put in new pcv nipple and hoses).

The car drove fine, actually I put in new plugs and dist and cap and it felt so so much firmer.

Bad oil trap? I put a few drops of Gunk engine cleaner down in (engine off) and drained the oil. I've been meaning to clean it.

Should I just do it right? Remove the intake manifold. Clean out the oil trap. I would like to clean the intake manifold too.
