First Engine Drop and Rebuild - Page 2

westyguesty · 09-07-2012, 02:36 AM

Located in Shropshire in the UK, doesn't seem to be many people running older 911's and even less working on them themselves in the UK. Would be useful though as another pair or hands and someone who has done it before would help. Also use of the odd tool would be useful. Good job I have you guys to help, otherwise I don't think I would be attempting it.

Got both books 101 projects and engine, nice and new and clean, sure that will change over the next few months

Feeling more confident as I get stuck in, but now I have the new studs, worried that at least one of them is broken very close to the block, time will tell !

Good luck I have 3 broken head studs, but... I keep using it trying to save some money to rebuild it!

Not much progress as I'm still waiting for my replacement high lift Jack to turn up.

Just a few simple questions to help me on my way as I can't see much until the car is as bit higher.

Where is the earth strap and the speeding cable. Can find any pictures for them in 101 projects.

I thought I would remove the bumper while I wait for the Jack, all off apart from the three screws holding it to body behind the oil tank. Anything obvious I'm missing.

It feels close now

Earth strap is near the rear transmission to body entrance bolted to the body and to a transmission mounting bolt on my SC. (under the car)
The Speedo wires are disconnected in the shifter tunnel in the back seat floor beside the coupler and pushed through the tunnel.
Hope that makes sense.

Just curious, how did you discover that the head bolts were broken? I'm picking up an 83' SC possibly this week. Did you torque them appropriately and they turned?

Subscribed. I'll be doing this to mine at some point in time, so I'm following and cheering you on

almarmada,

You need to remove the lower valve covers (exhaust) to inspect the cylinder head studs or bolts. A visual inspection will show if all the lower head studs are still intact. I discovered one (1) broken head stud on mine when I did a valve adjustment. The barrel nut with a small piece of the dilavar stud fell on the floor when I removed the valve cover from the engine.

Do a visual inspection and if the owner would allow you to torque (test) the studs using atleast 15 foot-lb (well below the spec torque value) would be a good way to evaluate condition or status of the lower cylinder head studs. BTW, dilavar are non-magnetic material.

Thanks, already done the speedo then, was looking for a cable as well. Will have a look around for the earth strap.

almarmada, mine was making a strange noise, almost like a dry bearing. Removed the valve cover, and 5 broken studs dropped out. This was after a few hundred miles from a full service, then in storage for a few years. While I am enjoying trying to fix it, I wouldn't buy one without getting them checked !

Start looking for the 911 specific tools now. It was a bit of a nightmare to locate them when I did a rebuild.

Thanks for the other links, can;t ever have too much info.

Well it's down and out. Got my jack replaced and it was straight forward then. Only one part damaged and that was the rubber boot covering the gearbox rod.

Now more reading, but I guess it's seperate engine from gearbox, then remove all the tinware, then off with the CIS.

timmy2 · timmy2's Garage

Looking good.

You'll be glad you took them out together once you start cleaning, and especially when you are ready to re-install them.

Did you take off the clutch arm and helper spring assembly?
If not, do it now before you seperate the motor and transmission. (Ask me how I know)

What year is your SC? Perhaps you could add it to your user name info, makes it easier for us to know what you have when you ask questions.

Not had much time over the last few weeks, busy at work, but made some progress this weekend.
Gearbox off, CIS off and engine cover and fan.

Bit of a clean up makes it look faster already !

Removed the other cam cover and four broken studs that side, so only 9 broken ones then !

Removed the cam cover to see what tool I would need, looks like the old sort, even though it's a 1981 model. Just need to order the tool and a few more parts. Should the tensioner look like that or is it fully compressed. Chain seems lose on the top. Probably rebuild and fit saver collars to them

A popular upgrade is to fit later pressure-fed 'Carrera' chain tensioners. This might be the time to do it.
BTW, if you haven't done so already I strongly recommend you to join Impactbumpers. There are some very knowledgeable chaps there, and close to home too...
Good luck with your project!

Agree with those mentioning the literature on removal and rebuild. Its all very useful for the tips an steps as our cars get so much attention from us users. I've pulled the engine twice and I think the Bentley's procedure is the best. It misses nothing on my 87. I'm the sort that misses critical steps until I get extremely familiar and do something many many times.

westyguesty · 10-02-2012, 02:34 PM

I would like to fit the carrera tensioners, but just too much money at the moment. I have joined impact bumpers, just a bit quieter on there than on here

Looking to find the cam tools, and struggling to find many people selling them in the UK. Just an idea, would this work ?

If you didn't already look, the pressure-fed tensioner upgrade isn't cheap anymore. It ran me ~$2000US in parts.

Not as pricey on this side of the pond, in the UK a complete kit sets you back £620+VAT which translates to about $1000 incl. tax. Still a lot of money though.
