Maybe fuel pressure is too high, did your put in a bigger pump to keep up with that big old bridge port? If so, it may need regulated! I have a holley FPR on my stock port set to 2.5psi it has really helped it run smoothly. Hope that helps!

Why is petrol getting into oil sump


An older model engine with mechanical pump could have a bad diaphragm leaking gas into the oil. Newer engines with electric in tank pumps with gas in the oil are probably running way too rich or have piston ring sealing issues.

I have a 2003 Mazda 6i. I backed my car put today and there was oil leaking from the front end of the car and it continues to leak. What do do you think could be going wrong with my car?


DO NOT DRIVE IT UNTIL THE CAUSE IS DISCOVERED, MAZDA ENGINES ARE EXPENSIVE.
If it is just an oil leak from a loose oil filter , or a holed oil filter all you need to do is replace it. If the drip is from the sump plug it might need tightening or replacing. You might need to replace the sump pan gasket which is not a difficult job. If it is the sum pan becoming holed this is an easy repair. Might be dripping from the engine, this could be expensive.
It might be gearbox oil , this too would need immediate attention. Of course it might be from the powert steering pump .

Whatever it is, if the amount of oil is noticeable then your vehicle probably needs immediate attention

May seem like a slight over reaction but in the last couple of months I have become aware of several mazdas with failed engines.

Sump oil leak


Better off replacing the sump gasket and sump plug washer before travelling. Working in public health I have seen many motor cycle accidents caused by oil patches on roads esspecially after rain.

Mazda mx6 1992 wont start and plugs getting very wet, prior to this problem was running fine. too much fuel getting in? plugs sparking ok.


Hi Mike,
Sounds to me as though you have one or more injector leaking. First advice is to check the oil in the sump. You may find that the fuel has leaked past the piston rings and contaminated the lubricating oil. Please make sure you check that out as when you replace the injector(s) and start up, if the oil is contaminated the engine may knock!

Mazda 6 2o diesel replaced turbo new unit same


There is a oil drain return from the turbo charger to the sump. If the sump oil level covers the outlet into the sump, oil will build excess pressure tin the turbo causing the sealing rings to leak oil in to the intake manifold. This would cause smokey exhaust and loss of oil. Try this. Drain the sump completely, refill with the exact quantity of oil to Mazda spec. Dip the oil and if the new oil level is lower than the full mark on the dipstick, you have found the cause of the problem. Mark this new level with a scriber or file and fill only to this new level. Hope this is the solution.

Oil leak


could be anything from description im fraid, if i was to tell you that if the top of yur engine is full of oil in the connection to the cylinders then it will prob be rocker gasket, however if the oil is coming out of the bottom of the engine then you might have sump gasket probs or sump plug malfunction, or worse case scenario oil seals for one of your external pumps. sorry i couldnt be more specific.

I'm assuming no-one deliberately added petrol to the cooling water. You'll probably find there's a heap of oil in there too. It sounds like you've got a cracked head or a dead head gasket. Pull the head off and check. You could also do a leak-down test or a compression test to try and tell where the problem is.

A note on the side - the car probably overheated BEFORE the oil/petrol leaked into the coolant. If you continued to try to run the car, the overheating would have got worse and worse - resulting in a crack or the gasket being destroyed.

If you're not mechanically minded, you've probably got a rather large problem on your hands and need to get someone else to look at it.

Sorry to give you bad news...
