Hello, My name I Randall. I will do my best to assist you with your question.
how much oil is leaking? very little ? Or do you have to add oil often?
So you never were able to remove either cover?
let me type up some info. back shortly
Ok, this is a tough question but will send my thoughts. At no time does a leak stay the same. Over time it will get worse. As you may know,, there are round openings down center of valve cover as well that seal of the spark plug holes from oil getting in them. I personally would just snug them down. many times this will solve most if not all the leak. many times the bolts get a little loose. i am concerned if not fixed, leaks continue, oil will eventually get into plug hols then cause running problems etc.. try snugging them down. Book time is around 3,8 hours to change both. gaskets do not cost much per say.replace them? thats the best approach but tightening down should? buy you some time. Also, oil leaking down outside of engine does make a mess, can get into aother items even start burning on exhaust. Snugging down? its a rubber gasket so you can snug a good ways. Normally leaking cover gaskets will not cause any more than i have mentions. worse case, oil in plug holes
well, at some point , if? the plug boots degrade, ignition can arc through the oil and short out and cause missing . I have seen this happen
VERY worse case scenario, never seen happen but must mention. IF? they begin to short out from the oil around plugs? you could? damage a circuit in one of the coil cassettes
They are expensive
$400? right on cue as far as price. snugging? very well may work. we are asked to try this often
yes, it can be over tightened but.. hard to explain as its by feel. Just dont start tightening down so hard that you feel the cover may crack. work in diagonal pattern
not really :( But.. even after accpet? you can still come back and reopen the post. I am on/off each day and here to help,
Question post remain open as we many times have customer come back needing assist
Hope all goes well and you can save some $ as well. Thanks:)
