Most say the felpro one piece gasket is the best to use, instead of the 4 piece. Any thoughts?

Tooch1 Agreed For the last few years since Fel Pro put out this one piece gasket pan gasket I have used on all my engine builds.
I would also suggest a thin,very thin,amount of RTV black on the gasket before you set the pan in place.Also extra bit of the black "under' the the front and rear "loops", to assure a great seal from timing cover and rear of the pan.
Good Luck.

Thank you Sal,
Will do! I'll let you know how things work out,

Hi Sal,
I have a quick question for you concerning the Fel Pro Gasket. Did you re-use your original oil pan bolts with the correct head markings?
I notice the bolts that come with the gasket are about 4 threads longer than the originals. BTW I decided to tackle this job myself in my garage. We've had some unseasonably warm weather the last couple days here in SW Pa. Today was in the 50's so I took on the job. Not too easy under there being 6'2"
I had to take the two upper control arm bolts out, and it hung down enough to let the pan out from under the PS linkage etc. I am having my mechanic weld in a patch, and I'll do the body work on the pan, and refinish up like new. I was hoping to use the original bolts. But, If means I'll have leaks, then I'll use the others. That Blue Gasket seems a bit thicker than the old cork style. (Will the Blue show between the block and the pan?) I want to have the car judged, at Chapter in the spring, so these little things matter.

Let me know about the bolts ASAP.
thanks again,
Tooch

Toch1, Yes the bolts are a little longer as the gasket is thicker and require the longer length,,Definitely use the bolts with the gasket.I assume the inside of the pan is in good shape.As suggested by dwa175 I think,be sure to clean the gasket surface very good,especially the front and rear loops.I have used metal sand paper (also wire wheel ) on the front and back to be sure the RTV and the gasket seats better.Have fun and be careful under the car.I am assume you have the car is up on car jacks.Take care, Sal C nosal1
Sal,
I was afraid you were going to say that about the original bolts. Oh well, I'm sure this won't be my only pt. deducts anyway. Yes, my pan lip is very clean, as is the bottom of the block. My mechanic is going to make sure the rails are nice and straight too. I'm also getting different opinions on using the sealant on the rails of the pan. My guy (and others) say it's only needed in the front and rear corners. .??
Thanks,
Jim

Tooch1, I use the black RTV as an assurance of a good seal between the pan and gasket.This an additional step I take to be sure I don't get a leak.I am too lazy to do this job twice,let alone once. It is your choice either way is alright. Good work and good luck. Sal C nosal1
Thanks,
I have the clear RTV Silicone Adhesive. Any difference in the black, or just your preference?

Tooch1 I use both RTV however,because the Black RTV I use has more universal usage and I have more confidence in it's sealing,however I do use the adhesive clear on special cases where it needs to be an adhesive sealant. No problem.Like I say the Black is also used where sensors are installed to prevent leaks like on O2 sensors.
