I think I may need some Artest money to get things in order on this car

.
Thanks for the advice John_AZ
I have the 944 hayes guide, but have not looked at the oil cooler part yet.
I will need to find step by step instructions somewhere for this job. Anyone out there have a link to a write up. Something with pictures would be very helpful.
Besides the late OPRV guide (that does not appear to be in stock) ,are there any other special tools I would need to attempt the seal replacements?
Thanks
