I got the head bolts out of my SR but can't get the head off - Zilvia.net Forums | Nissan 240SX (Silvia) and Z (Fairlady) Car Forum

I just need some help on ways to take off my head. It just seems stuck on the block, and I can't figure out how to pull it off. So if anyone has done this could you give me some ideas.

You say everything is completely off right?
If it seems to be stuck, take a rubber mallet
and slightly tape the edges around the head.
That should take it off.

Yep do what he said. Don't use a screwdriver or anything cause you could damage the gasket mating surfaces and then would require some work to make it nice again.

RedSuns · 09-24-2005, 09:05 PM

did you get the 3 10mm bolts also?

there are 2 up front about 2 inches below the top of the head on the inside of the timing chain area...and one small 10mm in the rear

240mph · 09-24-2005, 09:08 PM

Yeah I was thinking he forgot to take out some bolts.
Usually the head should come off easily with a slight tug.
Check the bolts RedSuns mentioned.

sub_version · 09-24-2005, 10:27 PM

Don't forget to remove the timing chain tensioner...

Irukandji · 09-24-2005, 11:06 PM

usually the head will be stuck there from being pressed on for how many years its been sitting inside a silvia clip. just go with the rubber mallet, if that doesnt work... then double check to make sure all the fasteners are taken off

justeno_heat · 09-25-2005, 12:32 PM

Yeah I took off the 2 bolts in the front but I didn't notice the one in the back yet. I'll go out and take that out then. The timing chain tensoner though, how do I take that out?

justeno_heat · 09-25-2005, 05:55 PM

Hey RedSuns, where is the bolt in the rear of the engine? I can't seem to find it anywhere.

*fliprayzin240sx* · 09-25-2005, 06:41 PM

Theres 2 bolts inside front of the head that attaches to the oilpump cover, one on the outside by cam angle area *look around the water neck*, another on the back side corner of the engine by the crankcase breather.

justeno_heat · 09-25-2005, 06:51 PM

I know this might sound dumb but where is the crankcase breather at?

*fliprayzin240sx* · 09-25-2005, 09:32 PM

Back right *driver side* corner of the engine

powerls · 09-26-2005, 09:34 PM

All I can say is "BFH." That should work just fine hehe
