My 04 LT 5.3L starts to overheat when it sits at idle with the A/C on. The only thing I’ve done so far is I installed a dual electric fans that pull a lot more air than the stock manual fan but even with this it still climbs in temperature. The only thing that I have changed to the cooling...
Yeah me too. But I would’ve noticed it when I backed out. I’m at a total loss on this and I really need to figure out where this oil is going. I use only Mobile one so it’s really expensive for an adding a extra 4 quarts. I just got back from about a 400 mile trip for Thanksgiving day and really...
And yes that’s a new built transmission. 4L70E. 5 plantary gear sets corvette servo bigger boost valve and a high performance Sonnax output shaft since the last build I blew out the output shaft on launching. I guess too much weight to horsepower
Coolant is good. Compression is an average of about 185 per cylinder. The oil filter is a good idea but like others have said that the underside would be coated in oil. Just to show that I’m not bullshitting here is a picture of the underside of the Tahoe. I honestly think it’s either going out...
Yeah I know I avoided a major problem.Oil pressure is nearly 40 psi at idle. It’s running fine. I haven’t checked the plugs yet but that’s a good idea. I’ve never changed the pvc. I believe it’s built in to the valve cover. You think maybe that’s where it’s going? After reading your reply I saw...
I’m sure this has been discussed before but I wanted to start a new post because my situation I believe is unique.
2004 Tahoe 5.3L with CNC ported 799 heads
Ok so I just changed my oil approximately 500 miles ago. So I’m planning on driving a total of 4 hours tomorrow so I decided to give the...
Other than not heating the throttle body, if I block off the coolant bypass ports will it hurt anything else? I live in Oklahoma and it doesn’t get cold enough for the throttle body to be heated. The metal hose is leaking and it’s cheaper for me to block them off than buying a new metal hose...
I have a 57’ Chevy pickup with a 5.3L swap and converted to carburetor with the Edlebrock intake and MSD 6014 control box. It’s got flattop pistons and a Howard’s cam .555 lift 267/276 duration. I’m having a backfire when I floor it from a stop. Holley says it a lean backfire. So they suggest...
Well I decided to go a completely different route. Being that the Tahoe is my DD I’ve decided not to do anything else. Recently I just blew up my built 4L75E which was really frustrating. If I add a charger or turbo I’d have to make some major changes to the driveline and for me this just isn’t...
I measured the alternator voltage at idle and it’s around 16 volts. Should I be concerned? I always thought that normal is around 14 volts charging. Any thoughts on this would be appreciated. Thanks
Hey thanks again. I was able to contact PML and they identified the rear axle as a GM 55T. This really helps me because even though the parts are hard to find at least I know what I’m looking for.
Ok thanks. I thought maybe a 50’s era GM tri-five but I have no idea but I really need to know what type of rear axle this is and if it’s strong enough for my project.
I’m doing a LS swap (5.3L) cammed up and carbureated with a TH-350 transmission in a 57’ Chevy truck. Now it’s possible that...
Can anyone help me identify this rear axle? I know that it’s a banjo style. At first I thought it was a Ford 9” but now I know that it’s not. Any ideas
