So Im Pretty Shure My head Gasket Blew And Now Have Some Questions
Does Anybody Know If Its Easier To Replace Gasket With The Engine In The Car or With It Out? And How Do I remove The Head Without Having To Mess Up cam Timing? Thanks

rogerz

easier in car. read up on how not to drop the cam tensioner out with a block of wood. If you don't move anything the cam timing will be fine. don't forget the two small bolts at the front of the engine. you may have to bump it with a piece of wood to get it to move. easier if you have a buddy to help (even a wife unit will work if she is sturdy). you can do it and leave the manifolds in attached.

..and I've got a question for you. Do you have a piece of software that capitalizes every word for you? I've seen it a thousand times where ppl can't be bothered to capitalize the begining of a sentance or typing in all caps...

@rogerz Where Can I Find Out What The Shape I Should Cut Out The Wood?

@FricFrac Im Not Sure If It Was You But Someone Else Asked Me Something Like That In Another Thread Im Sorry If It Bugs You But Thats How I Type Because Where I Used To Work All I Did Was Type Peoples Names In The Computer And It Just Got Stuck In My Brain To Capitalize Every Work Like It Is A Name But For You ill do these last words how there suposed to be.

Lol - I've done data entry too but you don't see me typing in all numbers....

Wedge is the shape you want.... a long wedge...

And remember, when you remove a bolt/screw you are only ****ing yourself in the long run but not using the correct size/shape.

Fail at "ill" Just teasing.

BTW their is a measurement in the FSM for the wedge if I remember right.

Is It Easier To Remove The Head With The Manifolds Or Seperating Then and Then Removing The Head
@FricFrac Lol What Does That mean????

This is a 280zx turbo right?

-Disconnect exhaust from bottom of turbo down pipe
-Remove all rubber intake lines / boots
-Remove distributor & wires
-Disconnect oil feed at top of turbo
-Drain coolant
-Remove everything else in the way (I don't feel like typing every little thing)
-Remove valve cover
-Install wood block in between chain (I have already posted detailed info on this process: https://www.zdriver.com/forums/240z-280zxt-s30-s130-tech-tips-275/aftermarket-cams-cam-removal-installation-pics-19939/)
-Remove cam sprocket
-Loosen head bolts in opposite order of install (see FSM)
-Hook up engine hoist / chain to head using secured bolts / hooks (this has been discussed before too).
-Remove head bolts
-Pull head off

Done. All this is explained in detail w/ pics in the FSM too.

I believe Fric Frac is typing in binary code, a reference to his previous post, very funny!

This One Is The Non Turbo One But I Imagine Its The Same Exept For The Oil Feed Line Part.

Sorry I Havent Updated But I Had My Internet Down So When I Got My Head Off And Took It To The Machine Shop They Found A Crack So I Had To get A New Head. I Am Going To Get One Of Of My 81 But The Bolts That Connect The Manifold To The Downpipe Are Stripped So I Was Wondering If Anyone Has Removed The Head While Still Connected To The Manifold And Downpipe Or Would It Even Be Possible Space Wise To Take It Out

Pretty Simple To Pull The Motor Out Imo, Since I've Done It About Three Or Four Times On Two Different Z Cars. Putting It Back In Is The Kind Of Complicated Part If You've Never Done It Before.

But If You Like Back Problems Like Nobody's Business, You Can Try To Pull The Head Off With The Intake/Exhaust Still Attached, The Head Alone Only Weighs About 70 Lbs, Unless You're Using A Lift, In Which, Pull The Engine Out
