POLL: Has Your engine died with less than 10k miles on it?

[Prof]

sorry,  i should have made it a bit clearer, i was refering to FD\'s,  my elford had nearly 100k on it and was still going when the turbo II engine went in.

Just out of interest Tony, since you have owned examples of all gens, which engines have the longest life ?

I would be interested to see a graph of power output against engine expectancy for each engine version, with details of those that fell above or below the trend lines - might help people gauge what mods are good and which are likely to result in premature engine failure (over simplistic I know - as the car\'s purpose and how it\'s driven and how often also have a huge part to play).

12a engines are by far the longest lasting, imo,

As far as i\'m concerned, more boost + less life

[Carl]

Many turbo 2 engines and EGI engines last as long as 12a engines.

Also this thread is not saying that all rebuilds don\'t last on FD\'s,but some don\'t.

There should be no reason why an engine should not do some decent mileage in fairly stock form.
If you have a serious modded car then the engine should be built to take it. Otherwise what\'s the point?

Maybe there should be a thread on how many miles have you done since rebuild?
Also how long ago was it built.

and who built it:2Mad

My first Egi did 156,000miles before loosing compression.
ANother I had (still in the shed) has about 127,000miles on it but is showing signs of poor compression.
THe TII had done 87,000miles and was killed by the previous owner running it without replacing the failing water pump.

 The running in period has a lot to do with how long your engine will last - as will the type of journey you do with the car.  Many of these cars were used as GT\'s when new and hence did lots of miles (I think my Dads did about 20000 in its first year?) on a regular basis.  Long periods of running at fairly constant temperatures and loads casue less stress on an engine (any engine) than short run times where the block never really gets upto temperature.  So as the cars pass form daily use into occasional \'weekend toy\' territory things start to go wrong, mainly through lack of use which allows corrosion etc to get hold - I know of some cases (On one of my Egi\'s) where the car was being used about 4 times a year - this caused all sorts of unpleasantness as the butterflies got stuck in the UIM and wax pellet on the mechanical OMP gave up etc etc....
 
 Find and cure the cause of the failure before getting the engine rebuilt.  IMO an engine that gives up after a fwe thousand miles has a lot of othe problems under the skin...

Yes mate - this is for the FD

Where does it say this for FD?

My FD engine hasnt died, but I voted for all 3 ! Had some other Rotaries.

[iaint]

Original engine failed around 40k.

Rebuild lasted 18k until it died doing 170mph at Brunters.

Next engine should last well

Antnicuk was saying this is for only stock FD\'s and thought I was giving the mileage for the TII

[tinker-27]

i brought my car with 67,000 miles with blown motor i think water seals,now going strong on v8 !!!

[antnicuk]

blasphemous words, how dare you use the word *8 on this forum!

[shaunwil]

I bought a car with a fresh rebuild off WGT. Never had any problems with the almost 3yrs of ownership. Do about 5k a year at weekends so just over 10 I would say (not very sure).

My 12a has done 106,000 miles. 1k of which weren\'t even on petrol I\'d love to have the FD on LPG and see how long it lasts with less detonation

I think the only other thing people don\'t think about is what is the quality of fuel like ?? Could alot of failures be due to buying naff fuel ??

Mine died at 49,000 miles. Water seal failure. After chatting to carl he made a good point about imports being started from cold at the docks, moved a few meters then switched off. Fuel sitting in the combustion chamber soaks into the water seals causing premature failure.

The recent Tesco fiasco shows how important this can be.  Imagine running dodgy fuel in a tunes turbo car... asking for expensive bills.

Mine always gets V-Power (and Optimax before that) and preferably fron a service station that I know is busy.

Petrol does \'go off\' - it loses Octane rating over time so a sleepy station that only refills it\'s super unleaded every month might be as bad as putting normal petrol in the tank!

But if Mazda are building cars that can go pop through a dodgy batch of fuel imho they want there fekin arses kicked!simple as that!
