Awesome oil pump love Melling products

I had a low oil pressure issue on a 2007 Escalade. The oil pressure was too low causing the Variable Valve Timing not to work properly. This set a check engine light and Stabilitrac warning message on the dash. I chose this Melling oil pump because I've had nothing but success using their oil pumps and this time was no different. I had 6 Psi oil pressure at idle before I changed the pump. When I removed the original oil pump, it was clear the O-ring for the pickup tube was bad. I installed the O-ring that came with the new oil pump and installed the Melling pump. When I started the car, I had 65 Psi oil pressure when cold. After warming up, the pressure was 22 Psi at idle. You will see the quality of the Melling pump as soon as you take it out of the box. It fixed the VVT issue and provides plenty of oil pressure throughout the RPM range.

Quality melling oil pump for l92 6.2 gm engine had an immediate increase of oil pressure on Startup and after engine warms up to operating temperature. I highly recommend for any gm ls engine definitely worth the purchase

I had used the wrong pump when I did my DOD delete and had low oil pressure. Getting like 10psi idle and 20psi while cruising. Now, I get 30psi idle and 50-60psi cruising. Very happy.

Worth every penny in my opinion. Could have gone el cheapo but i love my truck. Put this in a 2007 gmc sierra vortec max 6.0. Oil pressure would start at 39 and when fully heated on idle it was at 10-15. It was horrible to see. This starts me at 64 oil pressure and idle at 39 when fully heated. When i punch it she goes to 72. Amazing. Use the biggest spring. Already put 1000 miles on it and ita holding well. Im a diy mechanic. Took me a while to install. Harmonic balancer is a pain. Went ahead and did new timing chain and tensioner and of course ac delco. If you have a gm dont cheap out. She will appreciate well made parts. Truck runs better than ever!!
