Ok so I noticed a oil leak and coolant leak in a 94 accord vtec 170k it appears to be in the same spot cause there leaking into the same puddle but there not mixed, it looks like its coming from the area right by the oil filter. I heard the oil filter is connected to an oil cooler which has coolant that flows through it and oil obviously, but i just had the vtec solenoid and oil pressure switch replaced and I guess they had to remove the intake manifold to get to them, any ideas guys? thanks!!!!

this leak is not coming from above the oil filter? if it is then its a head gasket. if it is behind the filter you probably have other issues. pull your oil dipstick and see if its high (from coolant going into the oil raising the level) wate and oil usually seperate from the oil being heavier than water

It doesn't seem high, and the head gasket was recently replaced, the engine did however recently over heat a little not that much, and is there supposed to be smoke coming from the oil cap? it's not a lot but some...

If it was the HG wouldn't the coolant and oil be mixing before it leaked out?

first off clean all of oil leaking out. use break cleaner or gum cutter. pour small bottle dye in the engine oil. run it and check it with the black light..hope that help

youre correct that the oil would mix with coolant from the HG. however, you said is was leeking in the same spot but not mixing. i was thinking you meant the leak was on the floor in the same puddle. depending on what oil weight and what the out side temperature was if it was cold and a heavy oil you might see the funny looking colors as the water floats over the oil. thats what i thought you meant by not mixing. smoke from the oil cap is not supposed to happen- the oil is burning.sounds like a possibility for this is either you have bad valve seats or leaking seats and as the combustion occurs the oil on the cylinder walls is burning and extra smoke is coming from the valve seats into the head. honda valve guides do wear faster than most makes of cars and that is the reason i always replace them with new ones when i do HG services. the smoke also could be just combustion gasses and the smoke is coming up through the seats or guides as well. the over heating after the HG being replaced should not happen. the head should have had a full valve job and resurfacing in a machine shop before putting the head and HG back together. check that your oil filter does not have an extra oil filter gasket from an old filter. they sometimes get stuck on the block when you change the filter and your new filter has its gasket and you accidentally get two gaskets on there. the gaskets cant seal to other gaskets and you get a leak when you build up oil pressure. there is no oil cooler i see in the parts for a 94 accord both vtec and non vtec so i dont know where you got that info from or if its called something else. i do know that cars like the 94 prelude had them but i didnt get a chance to cross reference to see the exact term honda uses for them to see if that term comes up in the 94 accord parts. you had the HG done but you should not have had overheating after. i am guessin you bled the coolant system and changed the thermostat and fan switch and that your water pump is not bad so i would say if all that was done or is known to be good then your head should have had a valve job when you did the HG. i also use new head bolts when doing HG services on hondas and some other cars like mitsubishi and northstar engines and some others.

No the oil and coolant is leaking into the same puddle right in the area of the oil filter and also another small leak right under the timing belt, but the coolant is only leaking near the oil filter, it just appears to be coming out of the engine individually not pre-mixed, I will check the dipstick for signs of coolant, the oil did appear an amber color, but it is also newer oil. The head gasket was replaced 6-8 months ago the over heating just occurred from being low on coolant, but it didn’t get that hot, and the coolant was low after it came out of the shop, so I figured he just didn’t top it off.

Where else could they be leaking from? Oil pressure switch was just done as well, he did remove the manifold and put it back into place. The waterpump is new but that would only explain the coolant not oil if it was bad. Give me some ideas please!

Theres no smoke from exhaust and I will check for coolant in oil and oil in coolant any tips on how to do that would be great.

The oil is smoking from under the oil cap, is that a sign of coolant in the oil? and theres some smoke coming off the engine and you can smell burning oil but it might just be oil burning off the engine from the oil leak? Theres 2 oil leakes both in the back of the engine one under the drivers side corner and one under the oil filter area, i didnt see coolant today but im sure thats cause i checked when the car wasnt fully warmed up...

RICKSAUTOMOTIVE

no the smoke from the oil cap area should not be there. this is either smoke from burning oil in the valve train, or water vapor (steam) from water in the oil burning off since water boils at a low temperature. you now mantioned a new oil leak under the timing belt area--this could be the oil pump leaking and would explain smoke in the valve train escaping from the oil cap. your valve train may not be getting enough oil and the temp in there is getting too hot and burning whatever oil is in there. you may get scorched cams or worse soon if you dont fix this soon if you havent already scorched the cams and rockers

I smell oil burning so ill have the oil pump checked after work thanks!!!

dj00140

But i know valvoline just check my oil pressure and it was good,

how can you check an oil pump?

What else could be leaking oil drivers side back of engine by timing belt cover?

RICKSAUTOMOTIVE

oil pressure is one way. it is checked my removing an oil sensor and installing a gauge. maybe valvoline did check but more likely these shops just look at it and dont measure stuff this detailed. you could also pull the valve cover and run the engine and watch the oil come in the valve train. it should instantly start flowing (pumping) oil. just run it for a few seconds. maybe 30 seconds at most

RICKSAUTOMOTIVE

oh and the crank seal in front (behind the pulley) could be leaking.

RICKSAUTOMOTIVE

its part of the oil pump assembly

deserthonda

checked for what?? that would be a total waste of time and money....

if the oil lite comes on , then you chk the oil pressure,,..

you smell burning oil.. do you smell it coming out of tail pipe?? if so rings could be worn or valve seals,,

oil leak hitting the exh system when hot is going to have a burning smell..

clean out engine totally underneath as well,, add a bottle or 2 of oil dye, rin the engine and see where leak is coming from,

And on a final note,, whomever charged you and removed the intake manifold to replace the oil pressure switch and the vtec solenoid ripped you off,,,, there is no need to remove intake manifold to replace either one of those switches ,,,,,,,,take it back and have them diagnose it..

did they replace the oil cooler seal ??

dj00140

is there an oil cooler in my accord? thats what i was thinking it could be and no they didnt do that, if you check this thread https://honda-tech.com/forums/showth...2745784&page=3 I explain what happened, i told the mechanic i wasnt giving him $400 to replace the vtec solenoid gasket and had to call the police.

But i really need help oil is leaking from the timing belt cover area, oil and coolant are leaking very slowly from the oil filter area. Smoke is coming from the engine area and under the oil cap, im losing a lot of power!!! and the rpms are bouncing around periodically, also the check engine light came on for a few seconds today

This is my only car between me and my girlfriend and im screwed if it goes out nay help is really appreciated more than you guys know.

Im bringing it into the shop tonight! so they can look at it tomorrow.!!!

Can coolant and oil leak from the oil cooler seal?????

dj00140

bump, please give me some ideas? i know the camshaft, crankshaft or balance shaft seal or the oil pump is leaking from under the timing belt cover but could that throw off the timing and make my car run weaker??? I dont think thats where the problem is I think it has something to do with the oil cooler which is leaking antifreeze and oil? I am not sure that is the source of the leak but it is that area! i need input!!!
