Posted quite a while back about lack of power and coolant loss on my 3200GT. Nigelo and fews others gave some handy hints and just thought I'd say thanks and give an update. Prices listed are main dealer costs for anyone interested (which I prefer to pay than have the hassle of a 100 mile round trip to the nearest indy)



Loss Of Power was apparently due to a small pipe that creates a vacuum? A crack in the pipe was leaking air in and thus giving me the spluttering noise. Now sorted for minimal cost and power is back.



My worst fears were realised with the coolant loss: No external leaks - was the Head Gasket. Surprisingly cheap at around £285 for main dealer but I'm wondering what was involved in the 31,000 mile service 7 Months ago?



My Engine Warning Disco Light related to dud oxygen sensors, coming in at around £250



Brake judder is a result of corrosion on the discs. Dealer advises reskimming but had these done at the same time as the service. Costs a stonking £485. I don't drive the car every day and it won't fit in my garage so I don't see how I can avoid this ongoing issue? If the car hasn't been out for two days, there's was a noticable "Thunk" during winter as the wheels / brakes dislodge when the car first moves. Any ideas?



Final sting in the tail was corroded backboxes coming home at £1100 (they're not stainless?) How much are after markets in comparison?



Was aware Mas ownership would cost me money (which it is doing) but no doubt fall in love again once the power is back...

bad loser

Completely unhelpful advice here but I was told by the main man at my main dealer that there was no cure for this except to move the car slightly each day, especially after driving in wet weather or cleaning the car.

on the brakes issue. it may work if you roll the car to a stop. i think that brakes stay tight to the disc until the car moves again. if the car rolls to a stop then the pads should be clear of the dics.

Had same issue - pads were glued solid to disks and needed several clutch dumps to unstick them.

Suspect hot brakes are the cause, so I let them cool before stopping. Also try to roll to a stop or brake very light when parking. When parking at home on my inclined drive i roll back and catch the car with handbrake.

standard practice now

Out of interest, where did they let loose?
Usually at the inlet joint.

Haven't seen them yet, but will ask to before I hand over the cash.
BTW cash for Head Gasket turned out to be exploratory work only... thought it sounded too good to be true!.... Can only hope it's fine but the coolant's leaking somewhere!!

Will try the slow / cool brake stopping.

Before you splurge on new back boxes, it is a simple welding job to get them repaired. I know we live in a throw away society but £1200 vs £50 for a repair?

The standard back boxes are mild steel and rot from the inside out. You will not normally get more than 4 years use out of them and frankly repairing can only be a temporary bodge.

Why spend £1,200 on something that WILL fail in such a short time when Eurospares sell a pair of tailor made back boxes @ £650 in Stainless Steel that's guaranteed for 25 years? See them here

Although a little more sporty than the standard items these are not deafening "sports" boxes like larini / tubi etc and have no annoying resonating frequency that becomes a PITA after more than single digit miles. As such they are a direct replacement for the standard units and are perfectly suited to long distance GT driving.

I have them on my own 3200 for exactly that reason.

Hope this helps

When mine went I took them off and gave to a welder mate along with a sheet of aircraft quality stainless. Came back to me (albeit in his time frame, not mine) as better than new. They are now every bit as durable as Tubi's / Larirni's etc.
Total cost was about £20 on stainless and a few beer vouchers.

Have gone the aftermarket route.. Stainless with 25 year guarantee for around the same money.

Also headgasket concerns turned out to be a hose fastener....you're previous suspicions were right!!
