Yes, they tell me you should drop the steering box to make this a far easier job, it's big and heavy so I declined .
The oil pressure gauge's feed pipe is black plastic and the hollow nut that holds it in place was stuck fast on mine so I left it, doesn't seem to leak .
There are _TWO_ gaskets, I wasn't planning to touch the second one but it was *so* krispy I'm glad I ordered it in as I wound up using it, better to have a $4 part and not need it than halt for a few days whilst a lousy gasket comes in .
Get some Gaskacinch and coat both sides of the gaskets, let them tack up well before installing .
You'll need to use lots of elbow grease and wire brushes to carefully clean the machined sealing surface of the alloy canister housing, one nick with a metal scraper and it'll leak forever more .
I used a _new_ single edge razor blade to get almost the entire canister to block gasket off in one piece, I'll post pix soon . lots of wire brushing and some scraping to get the cast iron surface *perfect* ~ I use Ether (starting fluid) to dissolve the old sealant so it wire brushes off fairly easily of both metal surfaces .
I disconnected the turbo's oil feed pipe at the turbo and the bracket on the air cleaner's 'T' support so I could move it to help line it up, there's another loop typ bracket on the back of the engine I knew I'd never get the bolt back in once removed so I left that alone .
One of the 8MM Allen head canister to block bolts *must* be in place when you offer up the cleaned canister as it won't clear the steering box .
I do not recommend using any sort of anaerobic sealant on this job, God help you if you do .
You'll need two open end wrenches, one 27MM and one 24MM for the oil lines, I mostly used my old VW Beetle front wheel bearing wrenches but also bought a box kit of super thin stubby metric wrenches from Harbor Freight, they're very helpful in snugging up the various oil hose connections, & maybe use for the final tightening, maybe not ~ I'm still fairly strong in my decrepitude so I used them to tighten the hoses, needed the longer ones to get them loose .
Jack up and block the car well and spend some time cleaning the entire left side of the engine before you take it apart, you'll avoid getting oil and dirty bits into the internals of the engine, the open passages lead directly to the crankshaft bearings and I've seen way too many scored and damaged by dirt bearings over the decades to ever not clean first .
