CommanderCrazy Posted December 12, 2011 Share Posted December 12, 2011 So i just did a complete drain and change of oil in my car, after about 12,000 kilometers. The first thing i noticed was a sort of burnt smell, yet i have no idea why.Any car nuts here that can tell me whats up? Link to comment Share on other sites More sharing options...

Vindekarr Posted December 12, 2011 Share Posted December 12, 2011 Could be a piston issue, could be a gasket issue, I'd say get it seen to by an expert, it could be nothing or it could be a rebuild. Link to comment Share on other sites More sharing options...
HeyYou Posted December 13, 2011 Share Posted December 13, 2011 What oil are you using? Entirely possible you simply left it in there too long. Doesn't matter if you are using pure synthetic or not, oil accumulates crap, and the filter, depending on brand, doesn't remove all of it. (or in some cases, any of it....... Yes, I am looking at YOU FRAM.) Regardless of what kind of oil you are using, on an engine that old, change it every 6400Km at MOST. Use a HIGH quality filter. Stick with dino oil. (non synthetic.) That's what the engine was designed for, and really expensive oils just aren't worth it anyway. I have been working on cars for 35 years and some change. A fair chunk of that professionally.

Vagrant0 Posted December 13, 2011 Share Posted December 13, 2011 Every time you change oil you should change filter. Even if you havn't driven more than 6000 miles you should still change your oil atleast twice to 3 times a year. On an older vehicle which hasn't been regularly maintained, stuff like this is fairly common. Drive it for awhile and check the oil after a few weeks. If the oil (wipe the dipstick on a paper towel, put back in, take out, wipe again) looks dark after that short of time or has black specks in it, it might be a sign of something wrong with your engine and it may need to be cleaned and rebuilt. The good news is that unless you've been adding quarts of oil over those 12000 miles, your engine probably isn't burning up oil at an unusual rate, so the cylinders themselves are probably in good condition. Chances are that what you're smelling is the old oil still in the system, or you spilled some on the engine as you were filling up.. Link to comment Share on other sites More sharing options...
CommanderCrazy Posted December 13, 2011 Author Share Posted December 13, 2011 Well i took it into a mechanic today. Engine was declared a write off.Coolant system failed, it kept reaching ultra high temperatures and the main block warped slightly. Not much, hardly noticeable, but still enough.Up for a new engine :wallbash: Link to comment Share on other sites More sharing options...
PaladinRider Posted December 13, 2011 Share Posted December 13, 2011 Maybe its a VW thing, but Dino oil has caused a lot of problems lately. VW and Audi pulled Dino oil from their recommended list and everythings full synthetic. I'd just attribute this to OP's engine likely being from 76. The reason being is that the Dino oil was mucking with the integrity of the seals. If it wasn't changed to 5W-40 synthetic after the first oil change, it was bound to be an oil-eater. This is a great write up regarding oil. I recommend this to anyone who's interested in knowing what types of oil. Synthetic vs Non-synthetic, 5w-40 vs 5w-30 etc. Link to comment Share on other sites More sharing options...

PaladinRider Posted December 13, 2011 Share Posted December 13, 2011 Yes, that's what I said - up until recently VW + Audi started off with Dino, but over the years they've begun to realize that those that did not switch to synthetic after the first oil change had problems. You're definitely right that it is also the seals itself. Link to comment Share on other sites More sharing options...
