Blue smoke on cold start

[ford4]

Hi, I bought a brand new ranger 3.0l in 2007 and has been smoking blue on cold starts ever since I bought it. I brought it in for warrenty 3 times and still does it. They had replaced the pvc valve twice and retuned the cpu. After the third time they told me that it was normal to burn oil on start up. I was wondering if anyone has had any issues like this and if so what was the fix, because my local ford dealer can't fix it. Thanks in advance.

WRONG! You need a new dealer. Make sure you keep all repair/work order receipts to get this fixed by warranty. Typically blue smoke at start-up is leaking valve stem seals, as the seals get worse you will also see blue smoke on idle and when coasting. Oil burning will shorten the life of your catalytic converter.

I already tried another dealer and they won't touch it because I have an open warrenty claim at the dealer ship I bought the truck. My hands are kind of tied on this one. I think the dealer knows whats wrong with it and won't fix it because of the cost, and just said its normal to burn oil.

bullshit...my truck has 140k on it. no oil burns...ever. file a claim with the better business bureau.

Blue smoke on startup normally caused by bad valve stem seals. or improper workmanship with the cylinder heads in relationship to the valve oil sealing system.

If the dealership refuses to help? Bypass them and go over their head to the Ford district sales office, or their national sales office for aid. Sure they may be an "private" owned ford dealership selling under license---but if they get nailed by Fords own system to resolve issues and complaints? They risk losing that "Gold Standard" b/s they can brag about to future customers.

I agree you need to find another dealer. I work for a dealer and it just took me all of 5 minutes to find a TSB to fix your problem. TSB 07-22-10. It is caused by excess oil being pulled into the upper intake through the pcv tube. The oil puddles up inside the intake. The fix involves removing the upper intake manifold and cleaning out all the excess oil, then installing a revised pcv tube to keep it from sucking oil.

the dealer already replaced the pcv and tube with a revised one, twice.I would like to agree with that fix because i cant see a brand new engine having valve guide seals worn out already. My truck is now 3 years old with only 21 000km!! Theres got to be something else wrong with it.

 

[ford4]

so i decided to look at the pcv valve myself. I think this is the problem for sure because there was lots of oil all the way up the tube right into the intake manifold. Is this normal or is this my problem. Also when i took the clamp off i heard air leak out.

This is what I found on my truck although I did not have smoke out the tailpipe. I think this must be a design flaw on these trucks that Ford cannot figure out how to solve. My solution (so far) was to install an oil catch can.

I don't understand this. Are you saying with the engine off you heard air leak from the engine when you pulled the PCV hose off? If this is the case you may have excess crankcase pressure which could push oil into the intake and which can be measured to see if it is within spec.

 

[ford4]

yeah, when i took off the pcv valve with the truck off there was alot of pressure released. So what causes excess crankcase pressure and how do you measure it?

 

[Rearanger]

A defective PCV or blockage in PCV tubing and/or blow-by past the pistons or leak in the head gasket. I believe you can measure it by putting a pressure gauge on the oil dipstick tube, but I'm not sure as I don't think a normal pressure gauge is suitable. I would get a compression test done though. Talk to the dealer and explain what you discovered, but right now I wouldn't trust that dealer very much.

did you ever find out the problem, my truck does the same thing and also has alot of oil in the intake.

Oil Burning

Try putting a one way valve between the vaccum line that runs to the brake booster from the intake tube, have seen this on VW's and Volvo's where at start up the booster is holding vaccum and immed pulls oil out of the crankcase into the intake tube . European cars solved this problem using air box catch can. Or eliminate ported vaccum tube from brake booster and just go with the one line. Just a suggestion.
