Hi guys! since I asked you about viscosity between Mobil 1 and Pennzoil because I had a problem with oil consumption going up only when I switched from a brand to another, I started to diagnose some possibilities... (I saw my car from behind and there is absolutely no smoke from the exhaust at full throttle, de-aceleration etc)
First, the car always took about 1 qt of oil every 4-6k miles due to a small seepage from the timing chain cover gasket. Since maybe 5k miles now, the car seems to take about 1 qt for 2k-3k miles. Its a cadillac cts year 2005, 3.6l vvt engine. I have Pennzoil Platinum 5w30 in it, what is suppose to be in there (gm4718m spec).
The leak from the timing chain cover gasket concern me a little since I found something else, kinda related.. you'll see.
Below the plastic engine cover, there's the plenium. Below the plenium (intake), there are the coils and valve cover. Only the on the driver side, on the valve cover, its kinda cover of grease (or oil). Its always wet there so I decided to take off one coil to check under there:
As you can see, the hole for the plugs are clean. But its leaking around the cover where the coil fits. Is this a valve cover gasket related?
If so, is it a DIY jobs?
If I take off the valve cover, I would be able to take off the timing chain cover and change those 3 timing chains while at it and changing the timing chain cover gasket while I'm at it, do you think I should do it?
Do you think the small seepage from timing chian cover gasket and from the coils could lead to a 1 qt per 1k-1.5k miles?
Caddy dealer just check by eyes my engine and tols me its a ring and valve seals + gaskets jobs. 20 hours + parts + tax = 3600$ job.
I'm out of warranty... I really need advise guys!
Thanks, Mark!
