kosmic Posted June 14, 2008 Share Posted June 14, 2008 Went to change my leaking cam cover gaskets and when i took them off to my horror there was absolutely tons n tons of dried up oil crud all over the camshaft caps and the well of the cylinder head, absolutely shit loads of it!! The previous owner(s) hadnt obviously done any regular oil changes which really f*cks me off as to why people buy Supras and cant afford to run them properly neglecting the basics...yet i was left removing 300 miles worth of stupid ICE wiring etc when i bought the car money well spent ey? Anyway question: i removed most of the crud from the inlet camshaft side without tyring to let bits drop off into the depths of the engine. Is there anything i can use to remove/flush the crud or should i left it in situ and continue frequent oil changes? Im going to do the exhaust side gasket tomorrow so any advice would be appreciated Quote Link to comment Share on other sites More sharing options...

Massive benefits in terms of longevity, yet still people are too lazy/ignorant to do it. There are plenty of engine flushes around that'll remove built up crap from your engine. I've been using Wynns on my runaround car, which had taken similar treatment and it's economy has been getting better and better with each flush. You can get a petrol engine compatible one too, so I'd give that a go. Really shifts the crud. Quote Link to comment Share on other sites More sharing options...

The only problem with flushing that i can see is that the built up crud being removed and shifted around the engine and blocking up the oil galleys/filters and eventually the oil pump which has 0.003" tolerance Quote Link to comment Share on other sites More sharing options...

kosmic Posted June 14, 2008 Author Share Posted June 14, 2008 Wheres Cw when you need him So would anyone suggest leaving the crap in situ and keep flushing with just fresh oil. One of the mechs at work said put some cheapish oil in, run for 50 miles, flush, repeat agian with cheap oil, flush and then stick in decent oil ??

I feel your pain. After three years of ownership I still find bodges left by the previous owner. They drive me crazy. Quote Link to comment Share on other sites More sharing options...

Thats what i did to flush out the gungy oil. 50 miles sounds a bit much though to be honest. I would just go out for a drive for 15 mins, let her cool down then 15 mins again. After that flush it out. If the oil is absolutely manky i would do it again, if its reasonably good then its time for the good oil Quote Link to comment Share on other sites More sharing options...
Dan8 Posted June 15, 2008 Share Posted June 15, 2008 i remember going to view to motors i mentioned when where they last serviced both replied about the same only last weak when i checked the dipstick oil was not even registering at the low marking Quote Link to comment Share on other sites More sharing options...
Chris Wilson Posted June 16, 2008 Share Posted June 16, 2008 Leave it alone, next thing is you will have all this gunk blocking the mesh of the oil pump pick up gauze, causing poor oil flow and dead bearings, or it'll be through the oil pump, bugger the rotors and you will have front seal issues. It needs a full engine strip to get it out properly, the sump may well have a load in it, too, but usually it's cheap oil, the stock PCV system, and the oil contaminants settling inside the cooler cam covers. Ask anyone who ran a CVH engined Ford in the early eighties what cheap oil, the new fangled PCV systems, and a big area cam cover gave...I used to have to DIG this stuff out to even SEE the cam. venting to atmo makes a huge difference, I just hate PCV systems.

Chris Wilson Posted June 16, 2008 Share Posted June 16, 2008 It's a bit late now, but just run the cam box breathers to atmo, into a catch can, and block the PCV valve on the manifold side. Quote Link to comment Share on other sites More sharing options...
Swampy442 Posted June 17, 2008 Share Posted June 17, 2008 I too feel your pain mate, when I got me soarer first thing I did was change the oil and filter (something I always do when buying a car) and what came out can only be described as tar. Strangely enough one of the turbos let go about 2 months later. Toyota specify 4 or 5k oil changes for a reason... Flushing oils are a no no in my eyes, pumping harsh chemicals round your engine, then shifting the crap elsewhere Quote Link to comment Share on other sites More sharing options...
