Thanks for the video, I recently dropped my head off to the machine shop to be rebuilt and i got a call from them saying the hotspots i provided were 10 thou too big, spoke to the people i got them from and they advised they need hammering/pressing in. Glad to see I'm not the only one. I think mine were Britpart, they came in a blank box but said country of origin China, seems the Bearmach ones are from Turkey.

Thanks for watching. They need to be a tight fit as that's what holds them in place putting them in the freezer helps loads, bearmach has stopped trading now and most other companies just sell the britpart ones. 🙂👍

Cheers for the video mate I am just replacing my hotspots tomorrow and feel a lot better doing them now after watching you. Have you done a video on how to remove rockers from the shaft?

No worries and you're welcome. There's nothing scary about doing them as long you take your time you'll be fine. Sorry I didn't do a vid on the rockers (its about the only thing I didn't do) but again take your time be methodical keeping things in order and you can't go wrong. Thanks for watching 👍

When I rebuilt the front brake caliper's on a Discovery I put the caliper in the oven and the piston in the freezer. The piston's went in great. Maybe of you warmed the head gently (Subject to oven size?) to say 200degree C in an oven and froze the hotspots (as you did) the hotspots would drop in without the need for a tap? Another interesting video!

I did think about putting in the oven but the wife wasn't to happy about the idea 😀 and they was a bit tighter than I would of liked. I did consider using a torch but the uneven heat distribution could cause the head to warp.

Great video, thanks for making it! Did that fix your smoking problem? I’m trying to solve a white ish smoke problem that started at altitude, moved the truck to Denver CO which is up at 5,200 feet. Manual says to de-tune fuel pressure 3% per 1,000 feet. Had that done, had injectors cleaned, but now smoke is worse! Think it may be a cylinder head problem, hoping it’s as simple as this.

Thanks, it fixed the black smoke problem. Pure White smoke is usually unburnt fuel most commonly caused by retarded fuel timing have you tried the simple things first like changing the fuel filter or advancing the fuel timing?

@@retro.restorations I did, playing with it didn’t help much until I washed the cylinders down with a little solvent through the port for the glow plugs. That and 15 minutes of engine operation did it. Should probably change the oil again, though, oil plus solvent equals not good. Thanks for the tip!

To clarify; the problem was, I think, that operating overfueled at high altitude for as long as it did (200 miles) sort of saturated the pores of the metal inside the cylinders, cleaning them removed the excess fuel and it ran clean after that.

A heavy carbon build up around the rings or hotspots could of been your problem and the solvent cleaned it of I'm glad you sorted it👍
