Can anyone provide any feed back on the Ireland Engineering spin-on oil filter adapter please? I've seen a few comments on the Korman adapter which may/may not be available still.

Does anyone know of or use any other adapter or a complete filter assembly using the spin-on filter bowl? In this context I'm particularly interested in any European source ... always assuming quality and price balance versus a US source.

Many thanks.
 
Spin on oil filter adaptor

I have a Korman adaptor. It is a very nice well made unit. Unfortunately when I attempted to install it I found that the rod that the stock oil filter
housing bolts into could not be removed. I tried heating it - no luck. I contemplated cuting up an impact socket to make a special tool to remove this with an impact gun but on this note I gave up with the thought that I purchased this adaptor to make life easier.

I reinstalled the stock oil filter housing - anyone what to buy a Korman oil filter adaptor?

MF, many thanks for your reply. I have almost decided to change the filter head for a top bolt attach rather than add a spin-on adapter. Tim T

That may be just as well. I have a Korman adaptor, but removed it after the Fram 'High Performance' filter cartridge blew up and dumped several quarts of oil on my driveway one chilly morning.
 
Bill Riblett had written: "I have a Korman adaptor, but removed it after the Fram 'High Performance' filter cartridge blew up and dumped several quarts of oil on my driveway one chilly morning."

You know, I had this same problem on my Bavaria back in the early 1990's. I forget what brand of spin-on adapter I was using - seems that I bought it from someone in the Carolinas - would that be Korman? The symptom was that when it was cold (or what we call "cold" here in California), and my oil pressure would be higher, the seal between the filter and adapter would break loose.

My theory on why this happened was that my adapter had a smooth face where the square-cut O ring on the spin-on mated. If a shallow square-shaped groove had been machined in the adapter, allowing the O ring to settle down into it, outward movement of the ring would have been prevented. Most stock applications for spin-on filters have such a groove.

After a couple of incidents of the old Bavaria puking out all of its oil when I was trying to get to work on time, I just put the old cartridge filter back on.
 
I have one of the later style top-bolt canisters from an E12 on my '74. The only shortcoming of the setup on a carbureted car is that the bolt can't be removed completely - it interferes with the intake manifold.

I use one of the copper-colored crush rings, they seem to be a little harder than the aluminum-colored ones, and I can reuse it many times without having to replace it. And I have a spare gasket or two on hand for the day when I'll have to remove the adapter from the block.

Charlie & Jay, thanks, the arguments for going with top bolt filter head now seem even stronger versus a spin-on adaptor although it just may be that Ireland have a version that is "safe" ... not quite closed that out.
 
I just did my first oil change since getting Tony's coupe last October (velocewest's 2800CS if you recall).

He converted to the top bolt style filter housing...
While removing and installing a new filter was a minor PITA, I could only imagine how it would be a REAL PITA if it had the bottom bolt housing.

The thoughts of remote filter (spin on) are appealing but seems like they are more trouble than they are worth.... maybe.

For now... I'm happy to have the conversion to the E12 style to (sort of) keep the mess manageable....
