Compression test worth it?

[Flex]

Someone once told me they're pretty pointless, who's opinion I would say is normally rock solid.

 

Just wondered what the general consensus is?

On the car your looking at its essential

If you have a performance issue or if you you have the plugs out for routine servicing, then why not.

I havent bought it yet Alex, I just wondered what everyone thought.

 

And as for performance issues, dont tell everyone!! lol.

Well if it's the car I'm thinking of (or a likely scenario)

 

Dan (Ekona) did, ended up buying a solid car

Torqen (octet) didn't, ended up buying a car that blew up.

I will always try and do a compression test if the owner will approve,and even better if you can do one cold and then hot it will give a good indication of bore wear and ring seal,but that's all, if you want to know more a leak down test is the way to go, but your not going to be carrying a compressor around.

I think at the end of the day, yes it's going to be worth it but the car is 20 years old, has had some good maintenance carried out on engine but it is 20 years old has been tuned upto 500bhp (then de-tuned to 385) any car that's been put under that sort of strain is going to have potential issues and there's no way to guarantee it wont go pop without spending gazillions.

 

I'll get test done anyway and just accept it will need a lot of money throwing at it in the future anyway.

Out of interest, what car is it?

[Grundy]

I'm now thinking R34?

[Flex]

R33 vspec

[Tricky-Ricky]

Both R34GTT and GTR have slightly better/tougher engines than the R33s, pop over to the Skyline forum if you want to pick peoples brains, although its pretty quiet these days.
