March 3, 20169 yr Evening all just a quick question for all you guys that work on scooby's alot. My recent purchase of a 2005 wrx 2.0 turbo has had a bit of engine work looking at it Mods that is.she has 100k on the ej20 engine with service history to back the engine up. My trip from essex to pick her up is about 600 miles round Trip. When checking car over all levels are spot on. Bit of a weep from one of the rocker covers but thats it. Upon checking today the oil is now below minimum. So maybe 750 miles since i got her the oil has gone from max to below min. no major leaks like i said apart from one rocker cover ever so slightly weeping. No blue smoke. My question is to you chaps is do these engines use a lot of oil when this sort of age and millage ? The weekend im going to do a compression test and inspect turbo for leakage. My other question is do the pcv valves block up on these engines ? Cheers chaps
March 4, 20169 yr That's a lot of oil to go through in such a short distance! I have a 54 plate Blob and i can go 6k miles and the oil will still be close to maximum!
March 4, 20169 yr I check my oil every fortnight and was doing 400 miles a week (til I handed my notice in last week but that's another story), and in 4.5k I used nothing noticeable Sent from my iPhone using Tapatalk
March 4, 20169 yr hiya, maybe a sticky PCV valve ( positive crankcase ventilation) . I had the same on my Outback on a trip to England, lost all in 700 miles, then hasn't lost a drop in 3 months. look up PCV it might be one thing to eliminate and may only cost around thirty quid. good luck, Alan in Belfast.
March 4, 20169 yr Author Thanks for comments chaps. Yes hopefully its the pcv valve. If not will have to do a compression test. And investigate the turbo
March 4, 20169 yr Author Thanks sandals will keep you chaps posted. The joys of all things mechanical
March 4, 20169 yr Some oil usage is fine. A bit of extra lubrication for the pistons. Your's does sound a bit much though Grease. So if it is the PCV valve, where does the oil go? Cheers Linx.
March 4, 20169 yr The pcv operates the breather system. It either goes to the intake or throttle body but I doubt you will lose oil through it. Not the amount you are saying. It should only carry vapors.
March 4, 20169 yr just for info 1 Litre every 1000 miles is the point at which subaru say the engine has a problem and needs investigating.
March 4, 20169 yr Author the turbo has had it chaps. Pulled the intercooler and pipes to turbo. Found a lot of oil inside compressor housing and intercooler.
March 4, 20169 yr Sorry to hear that. Could be worse though. Sent from my HTC Desire 510 using Tapatalk
March 4, 20169 yr That's a shame, at least it wasn't the engine itself! Can pick up a decent 2nd hand turbo or refurbed unit for not a great deal of money!
March 4, 20169 yr Author Cheers chaps and yes thank god its not the rings. Might go for the td05 turbo upgrade
March 6, 20169 yr I was going to say check the IC pipes for oil.... Mine has 147k and doesn't use a drop. I think I'm lucky...
