4JA1 and 4JG2 valve clearances?

**Hyakushiki** · April 9th, 2007 03:53 AM

Good day! Anyone knows the valve (or is it tappet) clearances of both 4JA1 & 4JG2 engines? Many thanks for the help.

Ang 4JA1 at 4JG2 ay .4 mm ang valve clearance

Tama si Fuego .40mm intake and exhaust valve whether hot or cold.

query lang sa valve clearance. sa adventure kasi, .25mm sa manual. pero yong mekaniko ko, .13mm lang binibigay sa sasakyan ko. sa 4ja1, may naka try naba na bit closer ang gap para ma reduce yong ingay ng makina. i just got a 2nd hand xto.

Metals expand on high temperature. So there is a possiblity that the valve will not seat on the compression stroke resulting in low power and excess smoke.

thanks for the info. i thought its just alright to adjust the valve a bit closer. i had L300 FB before, my mechanic always set valve clearance at .13mm and its doing fine. anyway, you know it better. thanks.

Ano nga po pala ang purpose ng magpaadjust ng valve clearance? makikita ba sa engine or kung saan man nakaprint under the hood yung valve clearance sa hilander with 4ja1 engine? para atleast kung sakaling magpa adjust ako sa mekaniko ko maituturo ko sa kanya na .40 talaga yung valve clearance ng para sa sasakyan ko. Baka kasi magaya ako sa case ni sir snowbound na iba sa original setting yung ginawa ng mekaniko nya sa adventure nya.

meron po ba sa inyo na pwede magsend ng manual for my engine ISUZU 4JA1 engine nung nabili kasi namin yung sasakyan 2ndhand wala na syang manual. eto po email ko kung sakaling meron po kayo Salamat po!

Kita ko na yung location kung saan nakasulat yung valve clearance hehehe.. nasa right side malapit pala sa air filter. Nakapagpaadjust na di ako ng valve clearance medyo malaki na pala gap ng dating setting ngayon normal na lahat ng clearance medyo pino na ulit yung andar nya.
