    Oil is actually blowing out the dipstick? Do you check the oil with the engine on or off? Because you are suppose to check the oil when the engine is cool. This is because the engine is cool and that allows you to know how much oil your engine has to work with - but if the engine is hot then there is most likely still oil in the engine and checking then will give you an improper reading on the dipstick.

Unfortunately you are going to need fairly major work. From the sound of it - the head gasket has gone - allowing the combustion gasses from one cylinder to get dumped into the oilways - pressurising your sump and probably spraying your engine bay with oil.
Being sluggish is lack of compression - because it is leaking internally - into the oilway.

It's quite a regular shop job, so get a few quotes before booking it in.

    The Pressure Control Valve is supposed to direct any blow-by and oil fumes back into the carb to be burnt - thereby reducing emissions. By removing the PCV valve, you can see how much pressure there is in the sump. With the PCV fitted - this will push oil into the carb and you will burn a lot of oil very quickly.

Blowing white smoke

If you have overheated your car recently, then you possibly have a blown head gasket. Take off your oil fill cap (with engine off) and inspect to see if there is a milky substance underneath the cap. If so, bad news- head gasket. You can also check the oil dipstick for the same substance to verify bad head gasket, but usually it has to be pretty bad (gasket) or driven for a while before exhibiting any signs. The oil fill cap is a pretty good indicator. With the car cool, you can open the radiator cap and look and smell for anything other than coolant (fuel smell or oil slick). If so, probable head gasket.

My 88 dodge dakota has a leak between the engine and the transmission. What could the problem be and how can I fix it?

If it is motor oil, it should match the oil on the dipstick.
If it is automatic transmission fluid, it should be sort of redish and match your "tranny" fluid on that dipstick.
If it is thicker than motor oil, it should be manual transmission oil.
Motor oil leaks from the "rear main seal".
Transmission fluid or gear oil leak from the front transmission seal.
All 3 of these can look like they are coming from about the same place, where you have said.
All three of these require you separate the motor and transmission to fix them, and that means taking the transmission out of your truck.
Pretty expensive if you pay to have it done.
If you take the " tranny" out, most shops will replace both seals (one front, engine and one rear, tranny)
Depending on how much it is leaking and other things, lots of people let it leak.
If you are using a lot of fluid, perhaps it\'s time to think about repairs.
Be blessed

Coolant level in resevoir keeps going down over 500 km of driving in 1990 v 6 four runner , truck runs perfect idels at 1000 rpm and thermostat just goes to half way

the only reason for your coolant to go down is that you have a small leak somewhere. check the oil dipstick and see if you have any antifreeze mix with oil, it will have a different color and feel.

The oil gage on my 2005 chevy trailbaizer is starting to act up sometimes by reading zero. The truck has 87000 miles is this something that can be fixed? I checked the dipstick and I have plenty of oil??

Most likely the oil pressure sending unit is going bad or has a loose connection,but it would be safe to have a manual oil pressure test done to be sure it's not a problem with the oil pump.

Oil fill light

i am pretty sure the oil light comes on when the key is turned to the ON position, then goes out after it starts (providing oil quantity is not low). if it stays on after it starts, then may be an issue with sending unit.

mention it to the dealer when you take it in and they should be able to further diagnose.

BTW, what service is it going in for is oil service was performed 5000 miles ago?

Oil leak

This is a maddening problem if you don't know what's going on. If it's like my 92 isuzu pickup with 2.3 litre engine, it's a vent line coming out of the fuel pump which will spit oil out. I had a very hard time figuring out why but finally read that there is a galley in the block where oil runs back to the oil pan. If it gets clogged, oil will come out the vent line of the fuel pump. I even took my head off and tried blowing compressed air and sticking various wires through the block holes near where the fuel pump mounts. Nothing did any good and I was sick of the leaking oil and having to add oil so I bought several feet of oil resistant hose at autozone and routed it from the vent line, back over the engine, and into the dipstick tube. This worked like a champ. No more leaking oil. No more adding oil. Make sure you trim the outside of the hose where it goes into the dipstick with a razor knife or similar, so it will fit tightly. Make real sure you use oil resistant hose or it will break down and get into your oil. Not good. Then use a tie wrap to secure the hose to something else like the brake vacuum hose to keep it in place. I keep my dipstick behind the seat and make sure it's cleaned before and after checking my oil. This truck doesn't use any oil to speak of now and I wish I'd thought of this sooner. Short of removing the engine and having the block flushed and cleaned I don't know what else would have fixed this problem.

Someone else said to replace the fuel pump to fix this problem. I tried that. It did not work. It still spat oil out the vent tube to the tune of about one quart every 150 miles.

I also replaced all the engine seals and gaskets. Front and rear main seals too which were also leaking. So now my oil leaks are a thing of the past. Good luck!

Today when I was driving my car it began to vibrate loudly and then it acted like it was going to stall. It sounds strange when it is running and when I press on the gas, it is sluggish, very sluggish

I'm wondering if the motor is shot. W/ car on level surface, check oil level (w/ car off, pull out dipstick, wipe off w/ clean rag, reinsert, pull out and see if oil level is low, or doesn't show up on the dipstick. How many miles on the car? It could be a major engine problem.countrycurt0
