Not sure, But my 91 has always seemed peppy for a C 3800.... I have driven other C 3800'* 88-90 and they were great, but just didn't seem to have it... I had a friend that had an Olds Regency C body with the 3800 C.... Man you couldn't even tell it was running it was sooo quiet... But it just didn't have any guts...

But, in order to help reduce the valovetrain friction I have actually thought about using the 93-95 Vin L heads with the Roller bearings instead of the Pivots... Don't think it would be a great diffrence, But something I would like to do...

interesting, is this something that you did on your own or is it a 1991 (or late 1991) thing?

Okay, I'm new here. I suppose this is explained somewhere, but how do you post a pic? Does it have to be hosted?

1991 was an odd ball year like 1995...

My 91 has the Maxifuse Relay center, all the same suspension components as a 92 Bonneville( Springs, struts and the like )... And as were were doing some research we found that the 91 Vin C and 91 Vin L actually used the exact same cam with the exact same setup... I was kind of shocked... My car is a 1991 Model with a Build date of October 1990, So my car was most likely one of the earliest 91 models made..

Yeah the Pics have to be hosted... I have found that www.photobucket.com is pretty good as its free... But you will have a max of like 25 megs I think... I have been using them for a good while now...

You will need the image tags

[img]The web addy of the Pic[/img] and it should show an image...

Interesting. I've got a build date of February 1991, so it seems likely that I'll have the L27 cam.

But as for the suspension, hmmmm: I wonder about the SSE. The LE may have had '92 suspension, but hmmm...

Free works for me.

Now, to see how it works for me.

With the intake off.


With the C gasket over the L gasket.

The PCV hole is .775". The closest expansion plug I found was 3/4", which was too small, so I tried RTVing it in. I found some Expand-tite repair 3/4-7/8" rubber plugs at the parts store today, back to the garage to see if that will work - not sure, because the hole wall is wider toward the end of the head, and there'* a pushrod right behind the hole.

The C engine is out. Found this during the process:

Imagine the part the light is shining trhough going all the way around. Apparently that was the knocking noise. But, would that cause it to stop running? The trigger is part of the hub, not the pulley.

It looks like all of the C brackets will move over to the L engine. The Expand-tite may or may not work - sticks out a lot. One of the expansion plugs popped out after curing overnight, so I either need to re-apply, or try to get the rubber piece to work.

Stupid question here.... Do they make a shallow freeze plug in that size... Or is that hole a jagged hole?
