Gettin ready to do cam swap on my 162k formula a4 was wondering if u should replace my factory oil pump..at idle on full temp it's a 40-50 psi and close to 80 full throttle
Should I go ahead and replace because of mileage or keep it and get new o ring..also going with a double roller chain will a certain oil pump fit better

Its kind of a crapshoot either way, your oil pump is probably fine but most will say to replace it. Im putting an oem LS6 oil pump on my 383 build. I bought it from ws6store for $105 and it came with an o ring. As far as the chain goes some double rollers require oil pump spacers and clearancing of the timing cover. Im using new oem gears and an LS2 chain.

I would get an ls6 oil pump. It's only 100-150 for the added security

I would swap pumps and just go with a LS2 chain. Use the money you saved no going double and buy the pump.

I already have the chain and it comes with spacers I was thinking about the slp oil pump I would assume sense
they offer it with there double
Roller

if you have a SLP double roller already go with the slp oil pump its machined to fit the slp double roller chain you wont need to use spacers

Would a jp performance chain fit the same if u no thank u

I think the slp double roller is a jp chain i would call SLP and tell them what you have, the SLP oil pump i think is a milling they do modify either the pump or sprocket or it might be the collar that comes with the kit that makes it all work not really sure. i bought the kit for my build and every thing worked out great with no clearance issues on the front cover.

I would for sure change it. With that many miles id be replacing everything I could while I was in there.

Ok thanks for info..and that's the game plan replace everything I can while I'm in there

There are some out there that argue on pumps due to using ported LS6 or HV pumps that end up with Pressure issues. Interesting thing so I am not going to tell you not to do it but just monitor it once it's in and see what it is running cold idle, hot idle, and under load conditions.

I ran into this when I did a swap @ 30k miles and worried bout stock 2002 oiling and was recommended not to do it and never any issues @ 47k. Oil cleaner then clean so MAYBE when I either put a different stick in there or look at a 402+ CID motor will change the oiling system.

Just IMO.
