Cool, just trying to suggest common circumstances where your piston melting air leak may have occurred - we don't want to read that it happened again after all you toil!
I appreciate that, It's more annoying not knowing what caused the piston problem, or the tappet problem, I'm not sure the two are related, I would love to blame fitter error for the tappets , the same thing twice cant be coincidence , maybe the engine would have been ok last time without the air leak, I'm going to be checking again in the morning
Hmm - that's what we said last time. And to icepug before his poptop blew off on a dual carriageway AND his engine blew up.
If you become neurotic, the van will never move again! If it blows up, it blows up (and Ade can buy a 1776 ). But it probably won’t.
Not on an engine I have built, but the 2.0l in the bus had when I bought it. It had been driven to Spain with, amongst many other things wrong, the cup and spring missing from the throttle linkage so 3 & 4 were doing all the work.
Just finished 1/2 fitting the temp gauge, just got to run the gauge cable to the rear In the morning,
12 o'clock (110C) is hot enough. The further it goes past that... I used to panic if mine got to 240F which is 115C. Keeping it the left side of 12 o'clock is best if only a little under. Yep, slow down.
248F/120C would worry me but if VW say it's normal who am I to argue. 1957 though. 65 year old advice?
120* is pushing it, but up to 100* fine, 115* if you absolutely must. Temps above are almost exactly what I get. Tootling along between 80 - 90*.
And oil was nowhere near as good as it is today. I wouldn’t let mine go above 110C, but it doesn’t get anywhere near that. Cylinder head temperature is more important.
Mine sits at 90 whatever I do, but I'm not measuring the sump oil, I'm measuring after cooling controlled by a thermostat on it's way to the bearings. I guess all I know is the cooling works. lol
Hasn't yours? All type-4's have them - oh - I forgot, lawnmower engines can't take the torque without throwing a rod through the case.
