Me valen los pistones de un z20lel para el let?muchas gracias

[@mehmetozturk8626]

hello, what should be the tightening torques of the piston rod bolts and crank bolts? do you have angle? While watching your videos, I thought that I could open the Z20LER astra h gtc engine of my own vehicle and opened it. I am replacing rings, piston rod bearings and crank bearings.

[@SuperRon]

For the Z20let it is: Tighten: 35Nm Tighten: 45 Degrees Tighten: 15 Degrees. Not sure on other models

[@jemelakhan4353]

Any idea what the torque setting for the oil cooler pipes from the oil cooler to the oil pump I can't seem to find any great vid btw

[@SuperRon]

Sorry cant remember off hand, think I found it on one of the vauxhall forums with a Google search 👍

[@vincedavies9848]

Hi what sort of price would this kind of rebuild/refresh cost me im in uk

[@SuperRon]

I think the machine work was about 500-600, the gaskets, belt and pumps were about 300, so with labour probably around £1500 at a guess

[@r.a.h7682]

aren't you afraid the paint disappears because it's not hate resistant paint?

[@SuperRon]

No I've done this for years, no problems

[@r.a.h7682]

@@SuperRon interesting

[@adamdiaz8442]

Hey Ron do u no of a book or guide to rebuild a c20let engine

[@SuperRon]

There used to be a really good website on the forums back in the day that gave you everything for the c20let but I think that's long gone now. I dont think any haynes manuals cover the c20let unfortunately

[@adamdiaz8442]

@@SuperRon Thanks I built a few xe many moons ago just wanted to refresh the old brain cells thankyou tho

[@mohamadboodhoo]

How much would you charged to rebuilt similar engine? I just had mine gone.

[@SuperRon]

Thanks for watching, it's not something I'd have time to take anyone elses cars on.

[@williamgallacher7462]

Am doing my engines soon how was it

[@SuperRon]

We've had a few setbacks on the way but it is all done now, there is a full build series play list on this on my channel 👍

[@MrBrentSke]

what is piston ring cap ?

[@SuperRon]

Not sure what you mean?

[@MrBrentSke]

@@SuperRon sorry for bad english what i meen what for ring gap thit you use but Nice video :) i gonne try same thing to rebuild my z20let :)

[@SuperRon]

Oh I see, sorry. I think I measured them at 0.017" - 0.018", this was a few weeks ago now. I didn't have to re gap any, they were all good enough, General rule of thumb is bore x 0.005" = ring gap for turbos.

[@MrBrentSke]

@@SuperRon thx very mutch !! :) Keep up good work !

[@thejeterlp]

So many things done wrong in one video... First, The bore gauge has to get zeroed in a micrometer. The tool you used is not anywhere precise enough. Second, Never ever use sandpaper to deck a block. Third when honing a Block, never stay on a spot. You have to do fast up and down movements. Otherwise the bore will be oval after your honing. Fourth, Never ever use Rod bolts or main cap bolts again. These are like Head bolts a one time usage product. Also new oil pumps arent that expensive. The Oil pump is one of the major things of an engine and I would never put a used oilpump on a fresh engine. Nevlock has Oil Pumps from KS in Stock which are cheaper as oem ones.

[@SuperRon]

This wasn't a precision matching video, the bore gauge was to check consistently down the bore rather than to an exact size, the block wasn't decked, just removed any odd bits of old gasket or corrosion from the water ways, and the hone was just a quick deglaze, nothing to take any significant material away. I do agree on your points.

[@thejeterlp]

@@SuperRon You cant take much material away with that honing tool anyways, but making fast movements is a must on that things, even when its only a quick deglaze mate :)
