Head job and Hylomar
Hi,

I've started reassembling the refurbished engine. I checked the manual and the other sources and could not see if we should - or if it is recommended - to use hylomar (or some copper spray) before fitting the head gasket. Logic would dictate no need but I was hoping to take on some knowledge from the experienced TD5 drivers

The use of it between the camshaft carriage and cylinder head I'm aware of, but otherwise I'm not certain.

Thanks Td5 110 Station

This needs an anaerobic sealer fitted as itโ€™s between two machined surfaces which is basically a cam bearing so nothing with any thickness. It cures in the absence of air.

Something like:

Hello,

I have always used Wellseal for this type of joint, I used it on my TD5 when fitting a new AMC head.

The main reason is you don't want any squeeze out of the sealant that could find its way into the oil galleries.for longevity it never seems to completely dry out. Just paint it on the face for sealing leave a few minutes and assemble.

Have used it with no problems for over 30 years, I was told it was originally developed for aircraft engines during WW2. Still use it on aviation engines to this day ๐Ÿ‘

Edit: On the cam carrier joint not the head gasket joint.
