Are engine oil leaks a symptom of age or mileage?

Simple fix.

Thanks Chris...but I ask myself is it really worth doing the fix for a truck that gets used 1000 miles a year at the most?

Really..Never had one go bad and I run my trucks hard and put a ton of miles on them....I might have replaced a power steering line on my 91 somewhere in the late 90's if memory serves...That's how long it's been since I've had a failure.

I had to replace one on my 1980 k10 but it was an aftermarket thing and was just a rubber hose! but thats way older than yall are talking.

WHOSE book was he referring to? I recall about twenty years ago I was reading an automotive magazine, may have been Car&Driver, and one of the editors wrote a column about his experience with a new GM car. He felt it had an oil consumption issue, and the service department changed the oil and filter for him in order to properly monitor the oil useage. He wrote in his column that when he checked the oil level upon picking the car up, he found it had been overfilled by a quart and reported that was how GM preferred to deal with his issue, by overfilling the engine to make it appear that his car didn't have a problem with consumption.

All GM service books as well as industry standard i dont think burning is considered "excessive" untill its like greater than 1qt every 600 miles or so. The saturn i drive is now at about a qt at that level but it has 225K on it. But even when it had 100k or so it would burn about a qt every 1200 miles or so. Father in law was a mechanic and owned his own shop. He was meticulous with maintence and did oil changes every 3k miles. He put normal miles on it. and in the eary to mid 00's that thing only had about 100k miles on it but burned about a qt every 2000 miles or so and he said it did from new. NOw that said i owned and still do but need to scrap it. a 1986 GMC s15 jimmy. it has 200k miles or so on it and did not use a drop of oil ???

Yep. I have had 4 GM's. Two burnt oil faster than gas. My last, a DOHC Saturn used a QT every 800 miles since 30,000 miles. GM would do nothing about it. One of the many reasons I will not touch GM products again.

Seems like every time i think about checking the oil inmy saturn i am 2 qts low!! and the thing only hold like 4.5 or 4!!! I am pretty good at checking oil but i only drive 50 miles a day so i only check every so often and i forget after a while and then whamo i am at the tip of the stick! ieee.

might have been a nylon or siliconized ring. seen those. siliconized rings and gaskets..e tc..

i replaced both the gasket and the o-ring that seals the oil filter housing to the engine block. i'm not sure what material the new gasket is made. the gasket is hard, shiny, and very stiff so the obvious guess is plastic. seems like a funny place for a plastic gasket, but the engine no longer leaks a drop of oil. yay me

now i get to fix the exhaust stud i twisted off removing the y-pipe. boo me

oh good then my yukon is still book, at burning a quart at least by 1000m

I have a 93 caprice with 350,000 miles on it and it does not use any oil period. I can buy parts most everywhere, and they are cheap. It does not use special bolts that I have to buy at the dealer. My Duramax has 100,000 plus Kilometers and does not use any oil.
Personally I can not think of one reason I would ever buy a Toyota or a Nissan.
Every engine will get an oil leak once and a while, a domestic product, you can buy parts for easily, except Ford of course.

i don't know if the "600 miles per quart" idea is an industry standard exactly but it is one of the criteria used to decide when it is time to rebuild porsche air-cooled engines.

i got the manifold off the engine block relatively easily, and tried to remove the rusted stud. i tried penetrating oil (again). i tried mechanical shock (i beat on the *$#^#&*$#* thing). i tried thermal shock (i flamed the *$#^#&*$#* thing). i tried foul language. i never got close to getting its attention. so, i took the exhaust manifold in to a machine shop. a new manifold is $191 from gmc, $130 in the aftermarket, and about $40 at the machine shop.

gonna have to get me a drill press. :thumbsup:

GM lists the 1qt per 600 or 800 think I have seen somewhere. My Saturn burns about the 1 qt per 600 or so. But you only see smoke when it starts cold when you start off. Or if you floor it and drop into passing gear while on the road while going within a few thousand revs of redline.
