Really burning oil now

[kosteniuks17]

Guys, my p5 is getting very oil hungry recently. I think my rings and/or seals are going, not sure im not really a mechanic. I just took it on a 250 mile trip and it drank through about a quart of oil. Its to the point now that every full tank of gas I use goes a quart of oil. Any advice you guys would have or am I in need of a rebuild at this point. Its been a great car and to me it just makes more sense to stay on top of the oil and make sure it doesnt get too low and just keep riding it till something gives. I am most likely going to sell it in the next few months but I really want to give it away in top condition. I am using 10-30 and dont know how i feel about putting anything thicker in it. I also add some lucas oil stabilizer every now and then which tends to help it out a bit. But are there any suggestions from any with past or current experience with this problem.

Buy a used motor and swap it out. A qt of oil at every fill up will add up fast.

Is it smoking? if not check the head gasket on the backside of the engine, thats usually where it goes when it seems to "dissapear"
If it is, then yea could be the valve stem seals or rings.

And I thought my 1.8 losing 1qt+ in 1000 miles was bad...
Like stated above if it's not smoking it probably isn't rings or valves. Check the oil pan as well and see if it's leaking there. May need to be sealed back up, although sounds like your issue is much larger than that.

I was losing oil too, and I assumed it was burning up. Once and a while there would be a few drops on the ground, but nothing major. After closer inspection, my oil filter had worked loose, so I tightened up, and haven't lost anything since. I do carry a large jug of oil in the back now, just in case.

Have you considered a piston soak ?

lts relatively easy to do (you just pour some stuff down the spark plug holes).

It might help free up your rings.

This is news to me. What product might I want to buy for such thing?

I'm pretty sure seafoam would work pretty good but there is special stuff made for it but I can't find the thread that named it.

You just pour it down the spark plug holes and let it soak overnight or longer.
It's supposed to help dissolve the lacquer that seizes the oil rings.

here's a link to the thread that talks about seized oil Rings:

Thanks! Although my oil burning is not as prominent as OP's problem. This seems like an easy and cheap enough option to help my engine perform better. Thanks PCB!

I use seafoam before and after every oil change, I don't want my ring seizing.

I used seafoam only once on my car (I believe it was last year) From what I can remember (correct me if I'm wrong) You put X amount of seafoam into the gas tank, and the other amount you suck up via you're brake booster line? Is this the method you're talking about when you do it after every oil change? Or do you do it the mention way above, putting it down each spark plug hole and letting it sit?

Seafoam can also go in the oil, it dissolves lacquer and sludge build up.
You usually use the can in thirds (oil, gas, vacuum)

That can be a bad thing if you've got 10 years worth of build up. That sludge and lacquer can actually be helping the seals do their sealing. Many engine seals can start leaking if you wash it away. Seafoam doesn't "wreck" the seals it just kind of exposes their weaknesses.

Releasing 10 years worth of buildup can be bad for another reason,... you could release a bunch of "blood clots" into your oil system.

The same thing can happen with the fuel system. Lacquer on the inside of the gas tank can release as goo and end up on the filter sock or in the high pressure filter ( fuel pump housing). Or lacquer in the fuel line can release clogging up an injector.

Now you've got me too worried to ever seafoam the car again :\

Yah I've seafoamed a few times before already. If you add the seafoam into the oil then your supposed to run it for about 200 miles and then change your oil and oil filter after. PCB I think I remember you saying you put it in your crankcase after you do your oil change. Im not sure if your right but i think on the back of the bottle it says run it a few hundred miles and then change your oil. I didnt know you can pour it into your spark plug holes, that just sounds scary to me. can you possibly hydrolock your car that way or no? Also be careful to those that are sucking through the brake booster line, make sure you have another friend who is in the car slowly revving your engine while you pour it slowly into your brake booster. when I was doing it I decided to shut it off while it was sucking in the seafoam and leave it for a few minutes and it probably took thirty minutes of cranking till it got fired up. After that I was like never again am i doing that again. Thought my car was never going to start again haha. Just a word of advice....

The seafoam website says it's okay to leave the seafoam in the engine oil if you keep an eye on the oil and its color.

The seafoam will continually dissolve more and more sludge until the oil is thick with dissolved sludge.

If your engine is clean, the seafoam will work to prevent any build up and won't foul the oil because the sludge has been removed.

Keeping an eye on the oil color is key.


Doing a piston soak is a separate procedure where using seafoam may work but using the specialize stuff is probably your best bet.

I have never done it, but I would think that hydrolock is a possibility. I would certainly do more research before I attempted to do it. ( but like I said, I can't find the thread that discussed how to do it).

I'm pretty sure my rings are fine being as I don't burn any oil at all and I'm quite confident in assuming that the seafoam in the oil all the time is keeping the rings freed up and clean.

That was all worst case scenario stuff but you've already done it once so if it was going to happen it probably would have happened then.

I read a lot of threads about it on this forum and the ONLY problem I've heard happening was when one guy had a backfire that blew up his air intake,... the air filter landed on the driveway beside him. ( even that may not have been the fault of the sea foam).

I remember a couple of guys saying their cars ran like crap after doing it but I'm thinking it had something to do with not being fully cleaned out.

I would think a second and third treatment in that case would finish the job.

If you are using the recommended amounts as a pre service cleaner then you need to change your oil within 100 miles of driving with it in the crankcase. Post service additive than within 3,000 miles.

Using it through the vacuum hose of your choice then you do not need to change your oil.

The key thing is to follow the directions and pour it in SLOWLY versus allowing it to suck from the bottle.

There seems to be other and perhaps even better choices of products for piston soak advocates.

I use it maiinly in the fuel and via the PCV hose on my engines. Never had any problems with this product.

 

[L0w_N_sl0w]

I burn about the same amount of oil as you do. ive tried 10w 30 oil, seafoam in the crankcase, piston soak, and pcv valve replacment. i havent noticed any decrease in oil consumption, i believe my oil consumption is due to stuck oil control rings that expand when the car warms up. My suggestion is to sell your car or start saving your money for a new engine!

Apparently the brake booster vacuum line is a better choice for our engines. It distributes the seafoam more evenly across all cylinders.

I'm just going to put this out there: I bought my car with 125k on it and seafoamed it around 140k. By 165k I was burning enough oil that there were huge clouds every time i started the car and had was burning a quart every 600miles or so. New engine came after that and I don't know if I will seafoam it again. It just struck me as sort of odd that it started right after i cleaned it. I've done that to my SVT contour probably 5-6 times over the years and never had an issue.
