Question about GMC Cars & Trucks
Leak is only present while engine is running.what are the possible sources?
Look this is how you diagniose engine oil leasks, First have the engine pressure washeed top and bottom, get it clean, then go to a parts store and install a bottle of die that glows under a balck light, drive the car a week and have a shop put it up on a rack and inspect the engine for arear's that glow, then you have a good chance of fixing the leak the first time around.

SOURCE: oil leak from engine filter
The problem here is the switch inside the oil filter housing, or one of the lines attached to the bottom inboard side of the housing is clogged (oil return line). I just had this repaired. The oil could not return to the motor freely, so pressure was building up in the filter canister and leaking from the cover. The switch is called the oil pressure regulator switch, I believe. The filter depresses a little button at the bottom of the filter chamber. My oil filter was damaged apparently by the use of non-synthetic oil by the previous owner. Please have this addressed as this can lead to engine damage due to oil starvation.

I own a '99 Isuzu Oasis, which of course is really and '98 Odyssey with Isuzu nameplate. 214,000 miles, Cranked it up yesterday morning after 20 to 30 degree temps that night....took middle schooler to class approx 3-4 miles from home and approx 1/4 mile from home- noted severe burning oil smell in cabin and smoke from under hood.. Got it home and observed 3-4 quarts of leaked oil on the ground where I had been sitting just 15 mins before. Thought for sure I had ruined the engine after seeing all the oil in the gravel. Could not believe the leak was so severe, considering this car still runs like a beauty and has shown no leaking or other symptoms in the days before this occurred. Got home later that day and checked filter thinking maybe it had loosened. It had not. Refilled engine with oil and noted oil not leaking or dripping but pouring through area at engine block and oil cooler juncture at filter area. Found this forum and a few others on line and followed the plan , AutoZone: loan-a-tool 30mm 1/2" drive socket is all you need to do the job, except of course the oil cooler seal/O-ring which I got at Honda for 3 bucks. Took me all of 45 mins...no need to dettach hoses and leak antifreeze, just unscrew the 30mm nut and remove the old gasket/seal. Be sure to remove all the pieces, Mine was hard and brittle and broken in 3 pieces. What once was rubbery/pliable would now snap like a pretzel due to age/wear. When I buy my next one of these, and I will, because it is the best vehicle I have ever owned ( and I have owned several Hondas and Toyotas) I will preventative replace this seal at approx 150,000 miles.... this was close to being catastrophic failure- Thanks to this forum and others for the advice-plan to put another 100,000 miles on this baby!

Sounds like valve cover gasket is leaking. It leaks down side of engine onto everything in it's path. Stop by a local parts store and have them take a peak, they'll be glad to help you out.

there is also a small valve body you are supposed to replace when replaceing the phasers... also there is a ssm for replacing the valve lash adjusters. alot of time the small engine tick you hear can be a cracked exhaust manifold too so checking those really close is heavily advised because the cracks are really hard to see sometimes. i have seen broken push rods on these engines and they can be a pain to pinpoint where the noise is comming from. hope this helps
