oil leak

I'm working on oil leaks in the oil pan and valve cover and I need to know if halomar can be used with the existing gaskets since they are only 1000 miles old or if they must be replaced. Also is there a product that might be better?

I'm adding this because I think you guys a are the greatest! When I had my XK140 Jag I could find no help. I'm new at this internet stuff but it makes my life easier to pull on all the accumulated experience.
 
I don't know if there is anything better than hylomar. Using it on gaskets that have already been exposed to oil may be alright as long as you clean them thoroughly. If they are that new and have been leaking already it could mean that you may have over-tightened the bolts when installing them first time around.
 
Just to add to what Steve said, check the flanges of the oil pan and valve cover carefully. If the bolts have been overtightened the flange can get distorted and won't seal right with a new or old gasket. You can carefully flatten the flange with hammers, dolly, and a good flat surface to check against. BTW, resist the temptation to bang out any dents in the bottom of your oil pan ... you could end up with fatigue cracks as a result.

For the valve cover I usually use RTV gasket sealer to glue the gasket to the cover. Then I use Hylomar on the head surface side. Makes it easier when you are taking the cover off for valve adjustments.


G'luck,
John
