As the title suggests last night i pulled up at my mates place to notice smoke arising out of the gap of the bonnet and gaurd, So i pop the hood and theres oil all aver my strut tower,plenum and battery. Big mess. Closer look and the dipstick is up an inch. Hmmm. Waste 2 cans of my good mate Seans degreaser and push the d/s down and cross fingers. Drive home later on. Check when i get home, All good. Went to the shops this morning and back, to pop the bonnet to find the same mess as last night and d/s out abit. Just letting her cool down now so i can clean up and inspect further. Hoping to get some ideas or suggestions towards the cause, All i can come up with is blocked pcv's or piping (New PCV's 6 months ago with cam cover re-route) Oil level was fine, changed 2 months ago (to be re-checked now obviously)
Excessive blow by? Done a compression test lately? Could be PCV's, but they blocked up awful quick in 6 months. If you remove the oil filer cap when the engine is running do you get a HEAP of air coming out?
When my motor was on the way out and i had a heap of blow by, I drilled out the "washer" in the PCV pipe to about twice the size, this stopped the dip stick being blown out, but as the oil was being contaminated at a great rate I spun a big end not long after, i often wonder if I changed the oil each week to keep it clean how long it would of lasted. Definitely check for other causes before taking similar action.
The hoses and fittings you used for your PCV reroute are much thinner than I have seen on any other car, that may be contributing to your problem.
do a comp test , as mentioned ,,, some times if you give them a hard time , ( like all day ) this will happen ,, it is not unusual for the dipstick to pop up , but the smoke is another thing , it seems to me that you bottom end is letting go ,, i suggest if you are running good boost turn it down to stock till you can fix it ... pvc's are new , well the bottom end is bye bye .........
Okay, just cleaned up my mess. Checked PCV operation, OK , Hoses not blocked or kinked. Checked oil level, Low and darkish colour,not too bad really. - Draining oil now and ill put some fresh stuff in shortly. Ill just leave the filter as is. Also on my pcv re-route ive used 6mm silicon hose from the oem reducer bit on the PCV to the bungs on the cam covers, i know silicon isnt ideal to use as the oil vapours discolour the hose but is there need to go larger i.d than that? Ill go and do a compession test later on today. I also noticed the rubber bit on the dipstick doesnt really make a tight seal, should i put some tape on it to tighten it up or if everythings functioning properly, there should be no need to? Oh and Alex the smoke was just the oil on the hot bits under there lol
"I drilled out the "washer" in the PCV pipe " look into it p.s , this was a quote.. not that i did this ..
which is btw officially called the flame arrestor. i asked about this earlier, you'd be best keeping that.
OK , then thinks may still be OK , but you may have a little to much blow by , but still... on my zed i use a spring on mine , it holds it down but if it needs to pop up it will and then go down again ,, you dont want to lock it in place , it will create to much pressure in the bottom end , if it wants to let pressure out , allow it to do so...
OK just for those interested, I dont believe the "washer" is a "flame arrester" it is used to regulate the amount of air flow back into the intake system by virtue of the hole size, when excessive blow by is happening and the dip stick is popping out and oil is blown out on to hot turbos alot of smoke is created and renders the car inoperable. To make the car operable you can increase the size of the hole in the washer to increase the air flow from the crank case to the intake system eliminating the excess pressure in the crank case. Of course you could tape the dipstick in place but this wont eliminate the excess pressure, this can cause seals to leak. The real issue is unmetered air causing a slight leaning, correctly operating o2 sensors should alleviate this, but as the engine is screwed and you are just trying to make the car operable it probably doesn't matter too much. This isn't meant to be a fix as much as a patch to a car spitting oil out the dipstick tube, the engines days are numbered. Hence eliminate other cases and confirm excessive blow buy before doing something like this. This is the flame arrestor btw: I also believe that it would help pull atomised oil out of the air from the crank case before entering the intake system for emissions purposes. Just my thoughts, would appreciate and constructive criticism, IE dont just say BS back it up with something.
ok brisz,,,,, im not going to get into this as i really cbf .. when you boosting ( under load ) whats happening to your oil in the sump ? and were is all you boost going ? just think about it .....
LOL sorry mate in the 5 minutes it took for you to cry I was else where. But do tell us where does the boost go ? Try to keep it constructive and on topic BTW, its forum rules.
ahhahahah yeah i tho the reply was going to be something like that .. all good man .. enough said like i said , would not be wise to do it to the next engine ................
