GePa Posted September 20, 2014 Share Posted September 20, 2014 Hello All, i have a R50 that was made in 1998; and every 621 miles is consuming about 1/4 galon of Oil. Is this normal? Link to comment Share on other sites More sharing options...
ferrariowner123 Posted September 20, 2014 Share Posted September 20, 2014 I would say no, my VG33 doesn't eat anything, other than my money, i'am honestly spoiled with how often i don't check my oil, i just change it regularly. -Kyle Link to comment Share on other sites More sharing options...
Rebelord Posted September 20, 2014 Share Posted September 20, 2014 1/4 gallon or 1/4 quart. Big difference between those. Sent from my Moto X Link to comment Share on other sites More sharing options...
ferrariowner123 Posted September 20, 2014 Share Posted September 20, 2014 I'd say he was talking about a quart every 600 miles, i don't think anyone would be concerned if a 1/4 of a quart left that often. Link to comment Share on other sites More sharing options...
GePa Posted September 20, 2014 Author Share Posted September 20, 2014 Argh this happen because i had to go from Liters to galon and from KM to Miles. 0.265 galons. Link to comment Share on other sites More sharing options...
mel.d Posted September 21, 2014 Share Posted September 21, 2014 My truck has 140k miles and burns roughly 1/2 a quart max every 1k miles. However it's not consistent. I've noticed that it will burn oil at a faster rate with highway miles versus city miles. Link to comment Share on other sites More sharing options...
adamzan Posted September 21, 2014 Share Posted September 21, 2014 (edited) What is it in liters and km? You'll confuse most of the muricans on the board that can't figure out simple math but that's okay Edited September 21, 2014 by adamzan Link to comment Share on other sites More sharing options...
fixinto Posted September 21, 2014 Share Posted September 21, 2014 (edited) make sure you dont have valve cover gasket leaks. Around that year its a common thing to need to change them. Also, if your driving it at 3 thousand rpm plus, try driving it at 2500 ish rpm, just leave earlier. If you still consume oil at reduced RPM, just "not as much by a small percentage" then ya its probably using it. Look at your tail pipe when u first start up in the morning and see if you get blueish smoke until it warms up, in that case probably valve stem seals. hope some of that can at least point you in the right direction. But im leaning toward valve cover gaskets. do you have any dots under the truck after you park it overnight? If they r leaking that much they r pretty bad, im betting when you get them out of there they will be more like hardened pieces of plastic than rubber seals. good luck with your pathy Pat Edited September 21, 2014 by fixinto Link to comment Share on other sites More sharing options...
Kingman Posted September 21, 2014 Share Posted September 21, 2014 One thing you can try if the valve cover gaskets are leaking is tighten the screws. Sometimes that puts enough pressure on the old gaskets to slow the leak pretty significantly. 2 Link to comment Share on other sites More sharing options...
01Pathmaker Posted September 21, 2014 Share Posted September 21, 2014 Are you sure those numbers are correct? If you were leaking that much (or even half that) you'd certainly know it. You'd be marking your territory every where you go, if it was from the valve covers, you'd be getting an unbearable stench (and would probably smoke enough to look like it was on fire every time you stop. I think if it was burning a quart every 600 or so miles, you'd be smoking pretty noticeably. As for tightening the screws on old valve cover gaskets, I don't recommend it, as over that much time the rubber becomes very brittle and I've seen many of them crack (which makes the small leak into a big leak).

Kingman Posted September 21, 2014 Share Posted September 21, 2014 Many have done it with some luck. Buys enough time until the gaskets can be replaced. For many it's a big job and they need to take the truck to a shop (usually big $$$), or take their time and tackle it themselves over a weekend or something. For others it's easy peasy. You don't want to tighten them too much otherwise yes, you can snap the gasket. As the gaskets shrink the once tight screws are now loose, which is why tightening them often helps. I agree though, that much oil pouring out of the valve cover gaskets would definitely be burning the nostrils. 1 Link to comment Share on other sites More sharing options...
GePa Posted September 21, 2014 Author Share Posted September 21, 2014 That's the funny thing. I doesn't seem to leak to the ground and it smokes white sometimes. Also on a side note when the oil level is 3/4 it starts to make lifter ticks. Link to comment Share on other sites More sharing options...
Kingman Posted September 21, 2014 Share Posted September 21, 2014 Is it losing coolant as well? Link to comment Share on other sites More sharing options...
01Pathmaker Posted September 21, 2014 Share Posted September 21, 2014 Hmmm, sounds like a few fairly simple checks are in order. First, if you're also losing coolant I'd start with a pressure test of the cooling system, then do a compression leak down test on each cylinder, if no coolant loss, than go straight into the compression test. A quart of oil every 600 miles or so is pretty serious. You say you get noise when oil level is at 3/4, meaning only 1/4 below full on the dipstick? Unless the motor is extremely tired, noise with only a slight amount of oil reduction is a big red flag. Link to comment Share on other sites More sharing options...
GePa Posted September 22, 2014 Author Share Posted September 22, 2014 I had a big leak of coolant, which was fixed, but now is leaking near the main hose of the radiotor small drops of coolant. So i will check again. Link to comment Share on other sites More sharing options...
Kingman Posted September 22, 2014 Share Posted September 22, 2014 That should account for the coolant issue. VGs almost never blow a head gasket in a way that mixes coolant and oil. Link to comment Share on other sites More sharing options...
rgallant Posted September 22, 2014 Share Posted September 22, 2014 Take a look at your tail pipe,when it is cold is there a lot of soot in there ? If your oil rings are iffy or shot, you can burn oil and not see any blue, but the cats will get clogged with it. If you wipe your finger around the inside of the pipe and get a lot of black could be those. The problem is your compression could be perfect, but the oil rings still be shot. Also take a look at the rear of the valve covers, both of mine leaked back there. But I agree a quart or liter every 600 miles is a lot. My 97 has a leaky valve cover gasket one the left side and I go through maybe 1/4 - 1/2 a liter every 3000 KM Link to comment Share on other sites More sharing options...

Precise1 Posted September 22, 2014 Share Posted September 22, 2014 One thing you can try if the valve cover gaskets are leaking is tighten the screws. Sometimes that puts enough pressure on the old gaskets to slow the leak pretty significantly. This! I have not replaced a valve cover gasket (other than aircooled VW) in 25 years, they are almost always loose and just need a hand tightening with a Philip screw driver. Making sure your EGR valve is working properly goes a long way as well... That's the funny thing. I doesn't seem to leak to the ground and it smokes white sometimes. Also on a side note when the oil level is 3/4 it starts to make lifter ticks. Just to get a little history, how long have you had it, how long has it done this and how many miles on it? No this is not normal, but if it doesn't get worse, it is bearable. As long as it isn't leaking... My father had a 1975 Dodge Coronet that burned 1 quart (1/4 gallon) of oil every 1,000 miles (1,600km) from the factory, brand new. It never got worse or better, it just was that way for the 170,000 miles put on it... B Link to comment Share on other sites More sharing options...

I guess i pushed sometime ago. So something is wrong. Edited September 23, 2014 by GePa Link to comment Share on other sites More sharing options...

Not going any further than 2500 rpm, and guess what the oil consumption was reduced to 0%. Link to comment Share on other sites More sharing options...

Quaintbucket Posted October 15, 2014 Share Posted October 15, 2014 Just curious, if you leave your pathfinder sitting for a couple days or more, do you notice an oil leak underneath? I had my pathfinder sit in the parking spot for 4 days without moving last weekend. When I drove it on Monday, I heard a ticking sound and I was like, "wtf??" and saw that I had lost some oil. Topped it up and it was fine again. Just curious... I'm thinking it might be a seal that shrinks when it cools down enough and then leaks... somewhere...

01Pathmaker Posted October 16, 2014 Share Posted October 16, 2014 Ticking could have also been valve train or lifter noise, as when left to sit for a while more oil drains down, then can take a while, especially if your a little low, to thoroughly coat the rockers and pump into the lifters (higher mileage engines more so than newer ones, as oil passages become more restricted, even on well maintained engines). 1 Link to comment Share on other sites More sharing options...
