Quick & dirty engine capacity check ?????

Post by Haans » Mon May 11, 2020 3:51 pm

Gents & others,....what is the quickest most approximate way to determine capacity?
Do not want to strip head/ heads,.....could open a can of worms like studs stripping ect,...ect
???? Pouring parifin into cylinder in a controlled manor . Taking note that on TDC the combustion chamber needs to be filled 1st,...then mmovepiston to bottom and fill,..taking note of what goes in ? Now we just need something that can measure accurately !

Any other methods ?,....fairly urgent. Thanks in advance

Find TDC of piston, remove spark plug, get a marked big siring or peppet fill to top mark, release slowly into plug hole till top of plug hole

Measure how much went in, subtract the amount in plug space and BoB's your aunty Joe.

I think

You remove the doghouse and then you look down in between the fins of the two cylinder sleeves. Then you start counting the fins from the casing, outwards. You will then see the one fin is a bit thicker than the other ones. If you get to that fin and you have counted 21 or less....nah I've got nothing. Weet regtig nie. :-)
