I just put headers on my 340. Looks like I'll have some clearance issues with the filter. Here are my choices:

Use the 90 degree adapter i have that I need to buy the $30 bolt(lost it a while ago) for, or...

Use the oil filter relocation kit that I bought years ago and never used.

The 90* would keep the clean look under the hood but be more of a pain(or would it?) to change oil.

The relocation kit is clutter but easy access is had to the filter.

Those with experience with both, which did you prefer? I'll gladly buy the bolt if that what I decide. It's not a factor in this.

Thanks in advance!!

For a 90 degree adapter you can make a sheet metal cover to go on the header collector for oil change time. Then when the oil drains out of the filter it does not get on the exhaust. Then remove the cove when done and no mess.

Less problem areas with the 90 adapter. More leak areas and clutter with the remote filter.

Noted.

Cool idea for the oil chute. Thanks!

If desired you might port out the 90 deg adapter as there are some very sharp flow impeding turns in there.

The cast spin on adapter (threaded center) has fundemental design and engineering flaws. The bolt on adapters, such as those made and sold by Canton, are much better.

This does not entirely solve the potential problem with the hoses getting too much heat from the exhaust. Even braided st st Aeroquip hoses will fail when subjected to excessive heat over time. The rubber inside hardens and develops microcracks. It took me a while to figure this out, but when I took them off the crackling of the brittle rubber removed all doubts.

So if you use hoses, route them carefully and protect with insulated firesleeve whereever you have doubts. A reflective fiberglass sleeve is helpful too, but may not be enough. All depends on the particulars.
