Today's dumb question #1

[Davo1805NZ]

Just got my Stag engine back from being rebuilt and paying attention to some of the ancillary items. My car had previously been modded to have the heater piping connecting into the right-hand water transfer housing, and I had intended to keep this, however on examining the mod I wonder whether I can be confident to re-install this part. The threaded hole appears to have been made well off perpendicular to the face of the housing; also the stub only goes in a couple of turns. Please see the photo - what opinions do people have about this?

An alternative for me is to take the unmodified housing from my donor car and fit this - so I have removed all 5 bolts, but it won't budge; probably due to the car having previously been stood in a barn for over 20 years. I thought I may be able to dislodge it with a sharp spank using a piece of wood, but no good. Does anybody have any suggestions for how to remove the housing without damaging it?

Just realised this is actually two dumb questions in one!

Thanks in advance.

I’ve not carried out this modification as I don’t see the benefit. Measured temperatures on my heads have not been dissimilar enough to be concerned. However, as you have that transfer housing cover off, can you not remove the existing threaded fitting and have it fitted properly? Drill out the faulty thread and re-tap it to suit another threaded nipple? It might need an adaptor, or use a metric nipple. Either way, as long as you end up with a watertight fitting and an appropriate (1/2” or 13mm) male connector it doesn’t really matter.

you will only get 2 or 3 full threads to mate due to the material thickness, has it been put in at an angle to give better clearance? I have seen them fitted square as they look like they should be, but what is best. if you want it looking right as allready suggested re fit using a larger bush

If it aint broke, dont fix it

Now seems to be the ideal time to get rid of the nasty, (and unnecessary) bodge. I think your hammer + piece of wood will release your spare transfer plate if you knock it away from the head at the hose fitting extension. It can only be held by the gasket. Alternatively, getting the existing one properly sealed off should not be difficult.

I have an original early cover with the plug. it it a parallel thread and the plug goes in slightly less than 1/2 inch or so. I did the mod and bridged the heads. get a block and hammer to remove other end cap. make sure all bolts are out . 5 I think

oh. since it is bothering u now. you should take care of it while it is off.

Thanks for all of the advice - while I do subscribe to the "if it ain't broke..." philosophy, I'm also conscious of the wisdom of dealing to anything dodgy while it's relatively easy to do so.

Cheers.

Fix it....it looks almost broke.

Yep. I got the unmodded one off the donor car, so will probably just fit that.
