The bottom engine gaskets have been replaced and…..success…..no more leaking!!
There are so many gaskets and O-rings that I am not surprised these engines leak.
These are the components that will be removed with the exception of the dipstick
First up was to remove the oil pan. The bolts are different lengths. I logged where each came from, but didn’t need to refer to it on re-assembly as it was pretty obvious which ones go where. Then removed the baffle.
Oil pan removed
The oil pressure relief valve hoses were brittle, so I just cut them (yellow arrows). Replaced with high temp hydraulic hoses. Also disconnected fitting at green arrow and the similar fitting at the front. Then removed the sandwich plate.
Sandwich plate removed. Now removed oil tubes and windage tray
Detail of oil tubes and mounting that are removed
Next was to remove the oil filter housing
All components removed
Here are the parts……
….and now cleaned up
Removed all the original black paint from the oil pan
and then painted with POR15 high temp paint. Will be using a re-usable Stat O Seal washer for the oil pan drain plug
Used this great gasket kit from XKSUnlimited. It had all the gaskets and o-rings that I needed.
Completely dissambled the oil filter housing to replace all gaskets and o rings
I think the main reason for my leaks is that all of the o rings were brittle. None came out without breaking.
Used anaerobic gasket maker on all gaskets
Re-assembled windage tray and oil feed pipes
For the sandwich plate and oil pan, I used thread sealant on all bolts as oil can leak past them if the gasket is compromised. The anaerobic gasket maker can also be used on the threads
Mounted sandwich plate and baffle
and then the oil pan
paying close attention to where the different length bolts are used
Decided to make the exhaust pretty, so cleaned up and painted with POR15 high temp paint
Used this paint on the exhaust and oil pan
Ready to go back in. I had the exhaust modified by removing the EGR pipes and adding bungs for an O2 sensor on each. Will be adding AFR monitoring in the future.
Replaced the seals between this exhaust and the length to the back of the car
While I had access, I replaced all the high and low pressure power steering lines….
…..with new
Also replaced the subframe mounts
This was also a good time to replace the engine mounts….
…..with new ones
Also replaced the engine timing veneer
and upgraded the sway bar bushings to polyurethane
Swivelled suspension back into place and then re-installed exhaust. After refilling with power steering fluid and Pennzoil 20W50 yesterday, I started up the car and ran it until up to running temperature and there are no visible leaks. I won’t be able to take the car out on the road until spring, but I am very happy with these initial results compared with the previous crazy amount of leaking.
