Oil filter adapter swap

[Akula69]

I have read the posts in the forum concerning the swap from a metric, vertical pre-1991 oil filter adapter assembly and the post-1991 assembly. While I know the changeover is possible with the right parts, has anyone actually done this? I am *not* talking about just changing out the center threaded stud so you can use the 3/4 filters, I am talking about the whole swap which rotates the filter 90 degrees to the rear.

The problem is: it appears the charcoal filter housing is in the way. If you have done it did you relocate the charcoal filter or use a kit to relocate the oil filter?

 

Thanks

I kept the threads the same however I am pretty sure I rotated the housing didnt swap anything though. My memory is not to good anymore I can go check if no one else knows. I will go out and get a picture for ya if it would help.

I rotated mine 90* when I rebuilt years ago without any issues of clearance using the original RENIX filter adapter. It's a little tight getting the filter out from the top but I've always just gone through the bottom anyhow.

 

That reminds me of how it's always been difficult to get a filter started in that truck. Pretty sure the threads are a little crossed towards the top... I should probably do the swap to standard threads.

I'm pretty sure the filter goes underneath the charcoal canister. Ive got the adapter off a HO and plan to do the swap soon. It cost me a total of $5 at the junkyard. My question is (not wanting to thread hijack) how the heck am I supposed to get a torx bit on it in there? At the junkyard I just took the engine halfway out. But on my truck it is TIGHT in there.

Why swap the whole thing? Knock off the locating pin and clock the filter adapter to any position you want.  Mine's been that way for 10 plus years and no problems.

Been there and done that numerous times. Just swap the "nipple" from the later engines on to your Renix oil filter adapter housing.
