Question about 1993 Jaguar XJ6
My engine makes a rattling noise when accelerating - listening rod sounds like it is coming from water pump, however since that is connected to engine block, who knows? Oil is leaking from the enging into exaust pipes on right side (if you are sitting in car looking forward) in area of third valve from front. There is also now two small hairline cracks in the chrome engine cover. The oil pressure gauge has (sine I bought it 9 months ago) fluctuated during driving, but in last two weeks has become progressively worse - lower more oftern. I put a quart of oil in it yesterday and it seemed to help. Any hints/insight?

I can make a couple of suggestions here. First for oil to be leaking there must be a leak from a bad gasket...either from the head, (hope not) or head cover gasket....easy fix. It may be as easy as tightening down the covers. I would change the head cover gasket and make sure it is tightly screwed down.
Second the correct oil is 20w50 and preferably not a synthetic.
You will see an improvement in the oil pressure if you are not using 20w50.

no there is'nt enough pressure underneath to make it leak try tighting up the valve cover bolts or just getting a new gasket about a $6.00 to $10.00 dollar fix depending on where you go

Get engine warm and do a compression test. This easily eliminates head gasket. Head gasket is a biggish job and time wasted if it is not the problem. Part throttle breather unlikely as this is a vacuum applied to the cam cover, so water is unlikely to get in there as the air is coming out of the engine. But, if water is in the inlet manifold, could it be the inlet manifold to head gasket? I can't remember for sure, but I think this is water heated? If so, that is probably your culprit. If not, it sounds like a top end water leak and unlikely to be head gasket, head gasket leaks nearly always show up as steam out of the exhaust - "white smoke". Hope this helps.
