Is your pcv working properly?

I’m surprised karthief didn’t give you the punctuation scpheal. Mine leaks a little too. But, a little punctuation goes as long way.

if his pcv was malfunctioning he punctuation would be better.
actually I only complain when it makes total nonsense.

So far so good. It's been in about a year and a half and isn't leaking. It's not in the instructions but it must be installed dry.

Do you put the plastic guide on the crankshaft, and slide the seal on ,or use a seal driver ,or do both?

Definitely use the plastic guide that comes with it to slide it over the crank shaft, and your probably going to have to use a seal driver to get it to seat all the way.

Use the plastic guide and the seal driver if you have access to one. I did mine without the driver and it doesn't leak, bet would get it if I had to do it again.

I used a 4" PVC plumbing cleanout fitting to drive in my seal. Worked out well for $2

Rear main seal still leaks, I even put the Teflon seal in ,my question is, do I have a bad crankshaft or is there something else causing this.pcv working good I am at my wits end about this.

 

[General karthief]

Did you use a repair sleeve?
do you have any pressure/blow by at the filler tube?

Did you put it on dry or oil the perimeter of the seal first.
You sure it's the RMS and not the intake, valve cover gaskets, oil pan or even the flywheel bolts?

I used two repair sleeves, and both leaked no pressure at all
