Work in progress: 620ti Of Doom!

Its the same as a 75W-90 gearbox oil

quick OT question, the porsche has a hydraulic damper on the cambelt tensioner, it asked for sae80 gearbox oil. why do you think this was so necessary, if there would be an equivalent engine oil for the job?
 
Random question or what Matt!

I think in an item as crucial as a belt tensioner, I'd take professional advice on what to use.
 
The caliper rebuild went fine, however I had some fun bleeding the brakes!

Pics coming this evening, when I can get them off my camera. Both sides were rusted badly externally, and internally the piston was lightly corroded, causing the sticking on the passenger side.

After mucking about trying to fully unwind the seized caliper, I eventually got it apart, and then progressively cleaned the piston using some brake fluid and wet and dry paper, moving from 240 grade to 800, then finishing on 1200 to give a good smooth appearance.

The only issue came about when rebleeding the brakes - for some reason now when I press the pedal with the engine running there is a 'hiss' and the pedal feels lower than before, although it still stops damn well. As I can't get the pedal to the floor, I figured this would be OK for now :D

Recommended over getting a new caliper - both sides took 8 hours in total including the nightmare bleeding. After a couple of days, they feel fantastic! So unusual being able to coast like never before :)
 
I wouldn't have minded one of those 620ti's myself. A few years ago, my sister had a 800 Turbo fastback, about an N reg I think. Same engine as the 620ti I believe. She loved it, and I must admit I quite enjoyed driving it when I had the chance, it did have quite a lot of acceleration :). My sister was quite upset when she and the lady living opposite managed to reverse off the driveways at the same time one morning and had a bit of a coming to - which gave the rear end quite a shunt! Made more of a mess of the other woman's Fiesta though! I sold the Rover for her on eBay in the end, I think the bloke who bought it wanted the engine to put in a Rover 45/MG ZS.:)
 
They're not bad for what you pay, the ZS I have now and driving a Mondeo Mk3 has made me see the ride is a little soft, so after being reunited it will be for long lazy drives and such. Just miss the noise really! :)

Always liked the 800s but they're going for quite a lot, and prefer the style of the 600.

Hopefully putting a forged engine in it sometime this summer, going for a bit more power now I don't have to worry about economy.
 
I give it a month before you moan about the fuel bills and sell it again :p

On another note, why is economy not an issue anymore?

Glad to hear you're getting her back though :)
 
Ex-missus living 30 miles each way away was the fuel bill issue, and with something like the ZS miles shouldn't be a problem as I can commute in that, and just have the Ti for long distances and car meets etc.

May even sell the Zed eventually, I was told by the guys on mg-rover that I'd always go back to a Ti... should have listened and got rid of her instead :D
 
Just sell the ZS. Seriously. Its gotta cost more to run two cars than a little extra in fuel for the 620 surely?
 
I had a 620ti, Nightfire Red, M reg.

I paid just under £400 for it, ragged the **** off it until the input shaft bearing finally gave in about 9 months later.

Good little motor, and not the first I've had with that engine - the torSen is addictive, too.
 
I really don't understand your attraction to rovers, but as long as you're not ignorant in your decision and that you're happy with it then good for you.
