I have the Rislone in there now with high mileage penzoil. The last 2 oil changes I did didn't look sludgey at all to me. I'm a fan of Lucas, used it in an older Camry and Altima many times with no issues. Haven't taken it to the shop yet, had a few other things come up and this hasn't gotten...

So the actual mechanic in the family pointed me to this, cam phaser noise on Fords. The noise is pretty similar. I'm going to take it in and see what we get. I also pulled the heat shield off the manifold and didn't notice anything unusual. http://www.youtube.com/watch?v=RCyXPvRILSM

WOW! I'd love to see some pics of that. They're ever helpful in resoration :thumbsup:

Thanks for the input. I did have the belt off and the noise was still there, I'll check for play in the pump though. It seems louder around the intake oddly. Probably going to drop it off at the garage for them to do the compression test and look at the intake/exhaust manifold, don't have the...

As for my knock/noise...I drained the Mobil 1 and filled it with one quart Amsoil, and the remaining with high mileage Penzoil 5w30 with an ACDelco filter. The old oil didn't appear to have any glitter in it that I could see. No noticeable change but I'm going to lightly drive it around for a...

Nice! Is that the 6.6L? I am the 3rd owner, bought it when I was 15, before I had a license ;-). I just really fell in love with the style for some reason. Just had my carb rebuilt but I'm having a secondary issue that I'm tracking down. I'd love to get the turbo rebuilt this year but we'll see...

I'll check it out. What should I listen for with a coil off and increased rpm, the knock to become worse? Just trying to understand what I should hear if it is a rod. Thanks.

It sounded like a roller coaster would sound being pulled up the hill. I'm assuming one of the cams with a noisey chain. I didn't rev the engine but I can try that again this weekend. Going to to an oil change too back to Penzoil dino just to see if there is any change. Might do half a bottle...

Pulled every coil and no change. While I had the resonator off I took a piece of hose and held it up to different areas of the top end. There was noticeable chatter on the drivers side between the intake and block. The vac gauge on the TB gave me 21 deg Hg at a steady rate. If I gunned it up...

Roger. I've taken it off before to clean the TB. So, should there be a vac line on that nipple? I don't believe the routing diagram shows one. The Chilton manual I have also showed to use that as a vac source.

Indeed it is! 1981 Pontiac Turbo Trans Am 301 4.9L 73k original miles. She's getting jealous that the TB is getting all the attention :wink: Thanks for the additional input. I did order the o2 since I'm almost at the maintenance interval, plugs were done when I bought it last year. I'll hold...

Reconfigured my Torque App. Here is after driving 5 miles yesterday, outside temp appx 70 degrees. Here are the results while in park and the rpm, hesitation drop occurs. I'll get on ordering the o2 sensor today since that is about due anyway.

Nice. Do you like the silicone vac hose? I've been thinking of getting it for my Trans Am

Thanks. It looks like Amazon has a good price on it. ACDelco 213-1551 OE Service Oxygen Sensor ACDelco 213-1551 OE Service Oxygen Sensor : Amazon.com : Automotive

Hrmm. So would the Delphi be considered OEM? DELPHI Part # ES20117
