Help needed on mounting oilfilter on 216Cu

[Phil Waterman]

Hi Pieter

I don't have a source for them but have given it some thought if I ever needed to replace any of them. Well I've through of two ideas and lets hear from the collective knowledge of MLU as to what would be best.

1. Get a cylinder head stud of the correct size but a little long. Put the stud in with a nut and torque the head to spec. Then put on washer or spacer to bring the filter mount to the correct height clear the obstacles washer filter mount washer and nut.

2. Fabricate a new bolt by welding another bolt head to head to the top of a regular head bolt. My first concern with this approach was taking the temper out of the head bolt. So thought of sticking the head bolt in water right up to the head and then arch welding the bolt for the filter on head to head.

What are peoples thoughts?

Cheers Phil

PS Remember that there are two different head bolt lengths used on the Chevy head.

I've done a trial of the bolt head to bolt head welding but have no idea what, if any, metallurgical effects it may have had. The basic welding of one to the other wasn't hard - create the tapered groove, weld them and dress the weld down. This was only done to satisfy my curiosity as a trial to see if it was possible to make something of the right size and shape, not actually used to hold the head and filter in place.

I believe I'll be in need of two of these special ones as well.

Would turning down hex stock on a lathe be a suitable alternative?

Any machinist with decent knowledge of metallurgy should be able to ascertain the correct material requirements and hardening if any. After that, a simple CNC lathe program and voila.
Get someone to invest and make a run.
