First please disregard that video... I am not going to say I know it all, but I do know quite a bit about the series I 3800's and hang with a crowd that loves them..

with the miles you have the upper can erode around the coolant ports for the Throttle Body, But the series I does not have the same type of failure as the Series II...

Being that you are at 200+K, I would say replacement can't hurt..

The aluminum upper that he described in the video, he states its from a 95 Park ave... Here is the deal on that, the L27 with the aluminum upper does not have an EGR, so there is no provision for it.. the 91-92 L27 engines did not have an EGR and used the aluminum upper intake.. and let me make it clear for everyone, the aluminum upper intake was only produced and used for the 91-92 model years....

The 1993-1995 L27 used the plastic upper intake and had an EGR, this intake had provisions for the EGR.. 1993 was a digital EGR and 94-95 was a Linear EGR, both used the same upper intake..

while you are doing this, if you do this I highly recommend that you do the lower intake gaskets at this time... The Fle Pro lower gaskets for your car should be $23-$25...

I will answer any questions I can for you so just ask if needed... I think HotZ28 is very knowledgeable with this as well..


On the oil pan, you will have to remove the starter/flywheel sight shield and if you have it, unplug the oil level sensor... In some cases depending on the oil level sensor you have, you may have to unscrew it to drop the oil pan.. Being that its a 94 the windage tray is built into the oil pan...

The oil pan gasket for your car should be in the $13-$25 range depending on the gasket you buy... Other than that its pretty simple to replace on the 94 Park Ave/LeSabre

Any questions, feel free to ask..
