I think it's in the best benefit for D16Z6 engine equipped vehicle owners to start this new post on possible oil leaks (whether common or uncommon) a D series engine may have.

I'm curious to the fact that my D16Z6 is leaking but is a bit confused where it originates from. So if we can all generate a list of the seals, gaskets, and rings this engine has, that would be very helpful.

 

To my knowledge, the seals And gaskets I know that could cause oil leaks are:

Valve cover gasket
Spark plug seal
Valve cover bolt seal
Dizzy O-ring
VTEC Solenoid Gasket
Internal Cam Seal
Front Cam Seal
Rear Man Seal

 

I have a D16Z6 as well and I'm having the same problem with mine. The motor has always run strong and smooth, and has been well maintained. Looking into doing a head job though this will be my first. Other than what my manual tells me, is there anything I should keep in mind when doing this?

also what is the best way to get everything as clean as possible? Might as well make 'er look pretty too.

Also oil pan gasket, oil filter, oil pressure switch.

 

My replacement D16Z6 has a leak around the oil drain plug. The threads don't seem stripped and I teflon tape them and use fresh replacement washers. I think the pan got dinged near the plug and it's a little deformed. Might have been a freak accident or maybe they're susceptible in this area to get bumped. I'm going to start using a little RTV to avoid the oil leaks in the driveway.
