My Viper Loves Motor Oil

[Dimitrios]

checked the engine oil last week when i was cleaning the engine bay and noticed it was 3 quarts low. today im driving around and noticed the oil light come one for a split sec when i shifted gears. got back to my garage and checked the oil. it was 3 quarts low again. i didnt even do 300 miles in a week except for some spirited runs with the boys last sunday. whats up with that?

Better start doing the obvious like have someone look at the tailpipe as you rev it up, look for leaks, check to make sure there isn't any oil in the coolant. My '96 only take between 1/2~1 quart between oil changes with 10W40 Redline every 4000 miles. MGH

 

[Dimitrios]

no leaks on garage floor....

 

[Viper Specialty]

Most definitely start looking for issues.

-check all external places it could go. (oil lines, cooler, oil pan, oil filter adaptor, etc) Also check coolant to see if it is crossing systems at the headgaskets.

-Check intake tract and oil/air seperator, etc.

-Check plugs, if you have one cylinder eating oil, it will be obvious with that kind of use.

That should give you the rundown if it is external, intake tract (crank case pressure induced) or internal. once you have that narrowed down, you can focus in on what it is.

I suspect it may be a valve stem seal. I doubt an engine as recently rebuilt would have ring issues, unless there was an issue to begin with.

compression leak down test

 

[nismobrown]

check inside both exhaust tips .if one side shows it's burning oil more than the other you might have one head supplied from new with no valve stem seals fitted at all .
this is hard to believe, but more common than you might think.if this is the case it is easy to identify and there is an easy fix without removing the heads.

SELL IT

 

[Marc Lublin]

If you don't see any oil around, take it to someone good who can do the proper tests on the motor. Too much oil in 300 miles.

 

[418viper]

might be the leak is only showing itself when the engine is hot or at higher revs when the oil pump pressure is up.
Any signs of contamination in the coolant (white milky fluid)? does the Roe have oil lubrication fed from the engine, if so you may have a seal leaking.

Sounds like when during the gas crisis in the 70's, I sucked out gas from my friend's car one week and put some in the next week to make him think he was getting better gas mileage all of a sudden. That was a riot.

So who's messin with you ?

I had the some problem it was the valve stem seal

 

[plumcrazy]

ya better sell that roe s/c cheap and fast...

 

[stangkilr]

you need to sell that car and get a 1992 corvette convertible...

 

[BlueGTS]

There is something fishy about this story. No way you were cleaning the engine bay.

 

[Viper TT/10]

what's your crankcase ventilation setup on your car? catch cans or back into the intake?

 

[PaViper]

wouldnt you think if there was that much going thru the motor, there would be smoke from somewhere, you would think that the exhaust pipes would have residue on them

checked the left air filter and the oil is coming out from that side...no catch can.

 

[BlueGTS]

You might want to buy the Roe crank breather that screws into the oil fill in the valve cover. I would be surprised if you were pushing quarts of oil into the filter but that is one place it could go and it would not show up on the ground or in a smoking car.

i remember you having a detonation problem before. all the oil is probably puddling inside your intake plenium and then into your cylinder causing detonation with your roe blower. it would probly be a good idea to take off the blower and see how much oil is sitting on that plenium.then clean it out. and also add a catch can before returning it to your intake tubes.

i bought it a while ago and doesnt work..still have loads of oil on my left filter..

Do a leakdown test first.
I have had to rebuild many engines over the years with ring failures due to over fueling. If the tune is not right the oil washes out of the rings and the cylinders wear.If you do not trck the car, odds are it is not a crankcase breather problem.

Valve guide seals can be another issue, if your leakdown is good, odds are this is the problem.

did a leakdown test and all is fine at 8%. its a DAMN valve stem seal!!! phsshhh

 

[gotV10]

what is the repair process for a valve stem seal?

 

[Viper Wizard]

what is the repair process for a valve stem seal?

I am replacing them by pressurizing each cylinder so I can remove the valve springs to get to the seals.

Simple fix!

 

[plumcrazy]

it really is a simple fix. nothing to worry about.

glad to hear it
