Warped Head, Remove Engine And Subframe In One?

[blue_vl_t]

Hey guys, my water pump split the other day and drained most of the coolant, i noticed quite quickly that there was a problem, but with a very tight inlet cam and some other tests done, its confirmed, my head is warped

What i'm looking at is using a engine crane to lift the body over the engine( no i don't have a hoist), leave the motor and box together mounted on the subframe, replace the head, reasemble and refit.

I'd like to know if you guy recon its the best way to tackle the situation.

only thing i was thinking is lifting the car that high, would the rear bumper hit the ground....maybe??

any help from people that have removed the engine out the bottom without a hoist would be appreciated also.

you might not get it high enough to clear the engine and that, easiest way is just to pull the engine and gearbox out as one that way you can still push the car around and steer it easy without having to fight an engine crane aswell

You could try and put the car up on ramps with the back wheels and stands at the front. Wheel a trolly under the engine and gearbox and lift the trolly up to the engine and gearbox, then lower it down to the floor. Then use your crane to lift the front of the car up high enough so you can roll the trolly out. The ramps under the rear wheels will ensure you dont scrape the back end of the car on the ground. Using a block and tackle to the roof to lift the car is another approach ive seen.

Its a lot of hard work if you havent done it before, so its a good idea to get someone involved thats has done it to make sure you dont un-necessarily remove things that dont need to be removed. You'd be surprised just how complete the whole assembly does come out.

GTRNUR, thats close to what i was thinking, because i only have to change the head it would be nice not to have to remove so much gear. still looking into it, cheers

You could take the head off with the engine still in the car..

But you have an engine crane obviously.. why try lift the car up? just take the bonnet off and pull the engine out the normal way.

yeah if you still have stock head bolts you can do the head in the car. bit trickier if you have studs but can still be done i believe.

I have thought about it both ways, done some searches on SAU too, i was originally thinking i would remove the head in the car, but after some reading it seemed some people thought it was easier to just remove the whole engine.......

Initially i was going to remove all head bolts and pipes etc and try are remove the head with the turbos and plenum intact, obviously using an engine crane or block and tackle, reassemble all gear to the new head, with jun cams, and refit.

I have removed this motor before and plenty of others amongst buiding a few rb30's, so i'm no stranger to the whole engine thing, just the 32 GTR engine / engine bay is kinda tight, just trying to see thoughts on the easiest way.

+1 for taking the head off with motor in the car,

or remove it by using the crane the way it was intented

Dropping the whole subframe from a GTR is the hard way of doing the engine.

Leave the box in and only pull the engine.

Heads in situ are not not hard.

Leave the turbos in place and undo the two four bolt flanges, manifolds stay bolted to the head

Strip the front and remove timing belt etc obviously.

Remove alternator and starter motor so you can get the intake side off easier.

With the intake side off the rest is simple.

I don't ever recall pulling an engine to do a head, I know it's common practice but unnessisary.
