I am worried that it is the head that the lifters are loose or something. My air cleaner gets oii on top of the TBI almost right away. I was thinking the pcv valve might be upside down. Also It has gone through two radiators where it eats up the plastic where the cap seals. Now it has damaged a new radiator cap in just a week. However the cylinder compression is good at 170 170 165. It has 115K. I was hoping not to have to work on this anytime soon. The temp gauge seems to work ok as long as there is coolant and a good seal with the radiator cap. Any ideas?

What do you mean it eats up the plastic? That seem odd. Does it blow the cap off and lose all the coolant at once? Has it overheated at any time while you have been having this problem? Have you or Can you check to make sure that the temp is actually reading close to correct? Infrared thermometer? The oil on your air cleaner is almost certainly coming through your PCV valve. If it was in backwards you would never have any air moving out of it, it could be broken but Likely it is ok, you can test it by removing it and blowing air through it. Air should pass through pretty freely one way and not at all the other. I think they are really cheap and can be replaced easier than cleaned up and tested..... The real issue is probably either too much crank case pressure from blowby, or oil pooling in the head from worn cam journals....Since your compression numbers are pretty good (assuming the test was done correctly with a good gauge), I would probably be leaning towards cam journals..... However, both issues combined makes me think the engine might not be real healthy. How is performance? Does it smoke? Edited by Dystopiate666, Sep 7 2017, 02:58 AM.

Nothing you have said here has anything to do with the lifters. Sounds more like a blown head gasket to me. Warm it up with the cap off and see if you have bubbles in the radiator. Hot exhaust gas melting the plastic radiator? |

Yes Woodie unfortunately I think it has a blown head gasket. The gas apparently is so hot that when it escapes it makes a channel in the plastic seal under the cap. I hate to blow ruin this radiator as well. When I bought the car it had a notch in the plastic seal under the cap. But one thing that is bugging me now is that I let it run with water and a new cap for about 20 minutes and the temp gage was up. But when I went to let the water out of the radiator it was COLD!. The thermostate housing had gotten warm as expected and I thought the top radiator hose was warm. I had put a new thermostate in quite some time ago. This is really confusing why the water was cold. It has had a white gummy stuff in the filler neck from time to time so I think that is the old resin from stop leak someone put in there before I bought it. I would like to have it limp for a while. IT had a 13 lb cap on it. The new cap says .6 on it. Must be metric. |
