| RE: 390 Head Gaskets |

| Fel-pro makes two types of head gaskets...economy, and performance. You can see the differance if you visually compare them. The performance ones (available from Summitt) work fine. The economy ones (usually what you get through UAP) are prone to failure with the slightest bit of overheating. Now, if you are looking at delays getting this fixed, remove the plugs and crank it over to get rid of coolant in the cylinders, then spray WD40 in the cylinders and crank it again. But still don't wait too long. Finally, a bit of antifreeze in the oil is OK as long as you didn't "come on to it". Easy way to check. Drop the oil pan and check #4 main bearing cap. If everything there looks fine, then the rest is probably OK. #5 gets the lowest oil pressure, but it's a pain to remove in the car, so #4 is next best choice. And of course, if you remove the pan, you can check for bearing material in the sump. If you don't want to go through removal of the oil pan, then check dipstick......if filings are present, then you have to check further. If not, take the risk as it's a prety good chance everyting is OK. Lastly, run some cheapy oil through it for the first hour or so, then change it...gets rid of the antifreeze trapped in various places inside the engine where it shouldn't be. |
