Thread: overheating - loss of power

Cause I see no coolant in oil.

Been a couple weeks since car over heated and mia, well today I go out and check oil and there is coolant in the oil. Head gasket right, or would a warped Uim plenum do that?

Had loss of power, top speed of about 50. Shop told me the plenum was warped and needed a new one (~$330 kit), also new plug, wires, oil, and coolant. Half cost went to parts, other half labor. Took them about 6 hrs.

Your talking the plenum gasket right' aside from it being it being warped,
I know when my car overheated I could not go over 50, then it died on the freeway. I can get a new UIM plenum for 137.00 over here in seattle, wa. and fix it myself, just hope thats all it needs.

It's most likely the lower intake manifold gaskets if it's in the oil.

Oh thank god, it was cloudy and rainy when I checked my oil dipstick, I think my eyes were playing tricks on me, looks like new oil on dipstick, when I checked it a couple weeks ago I thought it looked rusty collored.

2 question's
Well eyes wern't playing tricks, I changed the oil to move car, and checked oil again, definate coolant in oil sign's.Havent done a compression check yet, can that be done with intakes off?
AZ looks to only sell lower or upper intake gaskets, can't find a kit online, does anyone have a link for one.

so I should change all the gaskets anyway since its that far torn apart anyway.
when I have the uim off can a auto shop test it for warpness, or do i test it while on vehicle?
Just hope the heads/gaskets are ok.
