I can't help with the crossmember problem but I can offer a suggestion. Lob a call into tech support over at Petronix, Jegs or wherever you purchased them from. If anyone has the answers you seek, they should.... Good Luck!! Hope you get it fixed without too much of a headache.

Thanks guys for the support. What do you think about motor mounts? I have a hard time believing that different mount manufactures would put out a mount that would change the clearance at the cross member to the point that would creat the problem I'm having. It's been to long to remember what mounts I have bolted in. Does any one know if GM still makes the motor and trans mounts anymore. I appreciate any and all insite on this.

I agree, I highly doubt the motor mounts would cause a clearance problem at the cross member. I used "Mity Mounts" on my car without issue... Ames Performance has the original style motor mounts. PY probably does as well...

Mity Mounts. Premier. Pioneer. Whatever mount anybody sells all start out as Korean made mounts. Mity Mount takes a Korean made mount and adds a travel limiting screw in the driver side mount. Otherwise it is the same as the mount you'd find at any auto parts store.

One: sent pictures and description to Pertronics/Dougs, their response was basically "No one else has had a problem like yours" hmm, OK, that helps me alot.

Two: Tonight I went to change the break in oil and the filter- I used a stock pf24. Evidently I had not yet tightened the headers when I installed the oil filter mount and the filter. I could not for the live of me get the damn filter out, I could unscrew it, and I tried every possible way to remove it- to the right, left, up, down, cock it this way, cock it that way. NADA!
Had to loosen the header bolts to tilt the header one way a 1/4 to 3/8 inch to get the damn thing out.
All the other filters at the parts store were the same diameter.

Came home searched here and found this thread

Good info went with the PF61- should be no problem getting this one in and out.

Only question I'm thinking of now is will the oil capacity be the same? smaller filler = less oil? My gut says "yes, but not enough to really matter"

Just a heads up for those buying the D590's

FWIW a local Pontiac'er bought a set of the D590's after I told him that the fit was good besides the tranny crossmember issue. He had another set of headers in place but had lots of problems getting them to seal. He said this was the easiest set of headers he ever has put on. He did not have a issue w/ his crossmember. He's running a pypes X over. Thought it'd be fair to report anothers experience with the same product, as it was never my intention to badmouth Doug's just perturbed that my experience wasn't glitch free. oh yeah, his is a 69 GTO HT

Ahh, you found out the hard way that the PF24 won't work with these headers. I'm using the WIX #51045 in my car. Much better filter than the AC-Delco or Fram. Hard to say if this filter does have a smaller capacity or not. Could be but if it is, I don't believe it's much smaller. The Wix filter, like the PF61, is taller than the PF24 making it very decieving in terms of capacity. I'm willing to bet their capacities are very close. Would be a good test next time I do an oil change. I have an unused PF24 in my garage which I can't use anymore so I'll run a capacity test.

I had to use the equivalent of the AC Delco PF 61 on 73 TA with AC (and Dougs headers) as you cannot install a PF 24, I measured the volume difference between these two filters after cutting them open, the PF 61 holds ~ 0.2 quarts less oil. I still use the normal fill volume as I am not concerned with this small volume differenc

You guy’s are really starting to scare me with the fitment of Doug’s headers. I also have Doug’s but for E heads and will do a mock up tonight. Not coated yet so that’s a good thing. So the filter I should use is WIX #51045 That's napa Gold right?

Ps,

Don't have insurance yet so I bought a dog

[techteacher5561]

I haven't been back to put the PF61 on I know it will fit. Now after reading that the WIX or NAPA gold is a better filter I might go that route. Won't get to work on the car again until Sunday at best.
Decisions, decisions.

Nice prioject you've got going there 70 Lemans. Nice dog too. The Dougs are still a nice header. Mayne the installation instructions should have mentioned the possiblity of needing a smaller diameter filter.

Oh wait I didn't read the instructions- oops maybe they do say that,,,LOL!!

[SS-TA]

In the case of my 73 TA the filter issue exsists because of the AC Evaporator case, on the engine stand installing a PF24 was simple, the Evaporator case keeps you from installing the filter from the fender side of the engine (No AC likely PF24 would fit). The PF 61 allows for installation around the tubes.

techteacher5561,

Thanks for the complements When we build repair or just squeeze some power out of these old classics we need to know when to walk away. Come back with a fresh outlook. Works for me. Then again would be nice if stuff just fit right in the first place.

3 years later some gray hair even some blood spill but I'll never give up my dream!
