Does the left 3.2 Carrera intake manifold remove quickly?

I likely need to replace the six gaskets on the left hand side. This guy basically disassembles the whole mainfold assembly: https://www.youtube.com/watch?v=OVLkAfPUc-w I imagined undoing the 6 flange nuts and a couple of other bits to free the centre and lifting the entire left hand manifold assemb...

Re: How to stop fumes in cabin?

Depending on your MOT guy even if the hoses are removed the damaged/rusty heat exchangers may still be a fail. Hopefully he isn't aware of them and passes it. You need to get under the car and follow where the heat exchangers enter the sills/chassis. You will find a length or flexi hose about 6&quo...

are they removeable? Squeeze the sticky-out bit with pliers?

Re: 3.2 Carrera UK emissions fail

Searching for a vacuum leak I found a perished pipe. This is on the "vacuum limiter", right? Two pics here: https://photos.app.goo.gl/nna7GWkhfRtXsKTT6 Those clips look crimped. Anyone know what I have to order there in the way of hose and clips, and do those clips just squeeze off? I had ...

Re: 3.2 Carrera UK emissions fail

I’m with Chris on this having had hunting at idle on my 3.2. Replace the gaskets (12) and also the plastic spacers (6). As Nige says, spray some carb cleaner at each of the joints between head and manifold. Alternatively, get a smoke machine (I home brewed one) and test for leaks that way. Good luc...

Further evidence re hunting 3.2 engine and mysteries...

Here's a video of the 3.2 engine hunting at idle: https://photos.app.goo.gl/yJ1vFK3Eic1p2B6r6 This is a higher mileage car than the 2.2T and it's set up for track use, so it's entirely feasible it could be in worse condition I guess. Also we have a few mysteries in these photos... https://photos.app...

How to stop fumes in cabin?

On Mike Bainbridge's advice I ran the 1970T for 5-10 minutes this p.m. and as he predicted it might, the smoke eventually cleared - which was a great result! However the cabin was completely full of smoke despite the doors and windows being closed. I intend to drive this car to its MOT next week wit...

Re: What's the deal with 1970 seatbelt mounts?

Dave O'connor AKA Stretch on here is the resident seatbelt guy. Produces lovely restored original Repa belts. On my 1970 I have retractor belts made up from original Repa static lap and diagonal belts with new period correct webbing from Stretch. The retractor reel is mounted low on the inner sill ...

Re: 911T - any thoughts on engine noises. Main bearing?

I can hear a knock (barely) when you move to the left side. Might be low pitch sound and mostly rolled off due to microphone range. If much clearer/ louder in person, it might be rod knock. Use a mechanics stethoscope, or a long screwdriver at your ear, to hear it better. Just don’t get it caught i...

Re: What do you make of backdated Porsches?

It can all be undone and made a nice 3.2 again, costs but the bits that come off are worth some money too. The 3.2 must be one of the most boring of the flat 6 engine, no cam effect and no pops and farts, but, turbine smooth and constant pull in tall gears, will run on anything and dare I say 30 mp...

What's the deal with 1970 seatbelt mounts?

My 1970T has two makeshift bolts through the rusty floor and not reinforced, directly behind the seat, with a lap belt attached. I doubt this would restrain my lockdown belly in the event of even a minor collision. There's an unused bolt in the top of the B-pillar where i can mount a coathanger type...

Re: 911T - any thoughts on engine noises. Main bearing?

Sounds pretty normal to me too. Those Webers probably need setting up. Sounds like they're spitting back which suggests some throats are running a bit lean on idle circuit. 911 bottom end is very robust so unless abused doesn't normally give trouble. Can help with setup. Give me a shout if you're s...

911T - any thoughts on engine noises. Main bearing?

First real start and run of my newly acquired 2.2 911T - here's a video (click the speaker to unmute). I took this within about 1 minute of a cold start. It's been running within a couple of months and has new oil, leads and plugs. https://photos.app.goo.gl/bmEra73MHUFi2pjt8 Any thoughts or comments...

Re: What do you make of backdated Porsches?

Backdating is an important source of revenue for Porsche specialists, forward-dating having become deeply unfashionable https://pbs.twimg.com/media/CFRPxB7WIAALy2Q.jpg:large :lol: Ironically my 1970T has been forward dated with a whale tail, large rear reflector and recaro bucket seats.
