Getting the headgasket done on the hilux 3y

[@davidturner5418]

Cool, I've owned a 1985 Hylux with a 3Yfor nearly 30 years. Blown the head gasket 3 times. Fault always (no head or block warp) on the back cylinder. Found despite using pre-stressed bolts ya still need to do a 500k 5lb pull down (just like the old man said). I found the rear head bolts nearly 10lb difference to the others, that was 10 years ago. Running sweet ever since. Interestingly there is only about 5lb drop in compression between cylinders.

Really easy job to do such a simple engine to work on

Sir how to many foot-pounds for thithening the 3Y head gasket and type head gasket you use? Is that carbon type or steel type of cylinder head gasket? Thank you sir..

Salve, dalle vostre parti si trovano motori Toyota/Daihatsu 4y EFI benzina?. Grazie

I wonder why the intake ports are smaller than exhaust ports

[@unfinishedprojects7439]

I find it's pretty common, you wouldn't really want to have exhaust gases trapped in the cylinder otherwise it wouldn't be efficient

hi what kind of oil do you use for that motor?

Will run like a dream

[@unfinishedprojects7439]

Yeah it runs pretty good, need to fix the exhaust though because there is absolutely no back pressure

[@alexrainey2698]

Did you have to get the head resurfaced before replacing?

[@unfinishedprojects7439]

Narr mate, just cleaned and gave it a light surface myself, It was pretty well perfect already
