Thread: 3.0 TDV6 broken crankshaft / engine rebuild

Recently had the intake manifolds replaced after one failed.
Mechanic said (lightheartedly?) the crankshaft will be next, and I’ve been anxious ever since.
Wonder what the rate of broken crankshafts really is?
Obviously we hear more on forums about the engine failures from unhappy owners.
It’s the $30,000 question.
1% failure rate I will live with.
5% take my chances.
10% might be time to unload it.
Is the risk higher the older it gets or more km it’s done?
Is it particular model years or engines?
What does one replace a D4 with?

I am sure that is to replace a TDV8 with a TDV8 in a TDV8 fitted vehicle - eg RRS/RR

No. I was talking to Ian (owner) and we were discussing hypothetical options should the worst happen to my 2013 D4. I was shocked at how much cheaper he said it would cost compared to what I thought was a ‘going rate’.

Just to clarify further, TRS don’t do servicing anymore, but he gave the name of a place that’s done a few that he was aware of. Can’t remember the name sorry.

We discussed the matter at great length and he left me with the opinion that regular 10k servicing is probs the best thing that you can do. Apart from that it’s a 1-2% failure rate…I’m happy with those odds. If the worst does happen I’ll probs put in a TDV8

A TDV8 into a D4 has only been done a handful (if that) of times afaik. There was a thread on here where the bloke went through the process and cost >$50k iirc. His parting comment was…it was fun, and the vehicle is fun…but I wouldn’t do it again.

Hoping I’m wrong, or at least someone has figured it out well…and not in the $50k range…

Like anything (within reason), every time it gets done someone figures out an easier and cheaper method. The time and experimentation required to develop the process is what costs the big bucks.

Agreed. I was surprised as well. I can only tell you what Ian told me tho. I seem to recall him saying something like a low mileage TDV8 being sub $15k and less than $10k labour and bits and pieces.

I’m sure he’d have no issues discussing it if someone wanted to call him.

He did tell me that a 2013 with a blown engine was worth about $10k (assuming he’s talking about how TRS would buy it from me. Adding $25k for a TDV8 in my books makes it an affordable option given the price of a replacement car, if you’re happy with the car body and trans.

I doubt there are many second hand,low K's, TDV8 LR engines around.

I don't, these are toorak tractors and don't see high mileage usually.
