Just bought an adaptor for my compression tester. It uses the bottom half of an injector and reduces down from 22x1.5 through 1/2 " BSP down to 1/4 " gauge... :idea: The fitting allows me to have the option of leaving in the nozzle (for a quick response) or removing to leave a cavity to allow for Jake's oiled rings test :idea:
:idea: For good measure I bought 4 heat shields. Although these are brand new they need to be cleaned because there are minute lumps of anti rust coating on the crucial sealing surfaces (which I reckon would be a possible cause for imperfect sealing) which over a period of time could lead to some of the nightmareish stories I've heard of carbonising of the threads :idea:
:twisted: Anyway anyone like to guess how much these 'shop soiled heat shields cost me? :twisted:

6 pounds, 55 pence each...just pulled that out of my arse

Wow, I wish I had a store you could shop at. I'd be rich! :) But then again, if you need something bad enough and can't wait you'll buy it regardless of price.
Cheers, Steve

This also is true in the department of individuals with special need, our daughters wheel chair, now remember this was for a 5yr old, cost us $6K, yes that is the write price, just for a wheel chair. Go figure. :evil:

I re-use mine. Before anyone has a heart attack let me explain.
The injector shield is designed to seal between the injector tip and the head. This keeps carbon from blowing up into the injector threads and ruining your whole day. Stripped or galled injector threads are a bummer.
So, When you torque down on a new injector seal it becomes slightly deformed, about .010". This pinching is what seals but because it is deformed it will not seal if used again. I turned a tapered tool to fit in an old arbor press, you could use a vice for this too. This tool reshapes the soft steel seal back to the origional cone shape so that the seals can be reused.
I have reused my current set about 10 times by using this method and have no carbon at all on my injector threads. In fact the anti-seaze is still silver colored. Heres a picture of the tool I made.

This is what I posted on another site (but I hadnt yet decided on method) I had been considering a hammer and dolly BUT
:idea: your way is more refined :idea:
"Actual price £10.61 convert into your own language ;o)
I will not buy those from there again. In fact I see no
reason to buy from anywhere at all. These were tarnished
with anti rust splodges and IMO could lead to the dreaded
carboning-up of the threads.
Now I have these new ones to hand I shall clean up old ones
and 'undistort' them to the same dimensions as the new ones.
I will even anneal them if required.
:evil: To put the price in perspective; this cost is 10% of what I
paid for the entire car some 4 years ago!! :evil:

:?: Would you recomend annealing? or are they 'stay soft'
Thanks :?:
