4.0 HC Cam

[TVR_nut_2008]

Evening Gents, opinions required if you're willing.

4.0HC 42k good condition, serviced well, goes well, appears looked after, engine sounds good and has had test drive and visual inspection by specialist - no obvious faults identified. Priced right for good condition car, but not if cam replacement needed soon. I've seen lots of 40 to 50k miles Chims that have just had the cam changed.

Based on the above, do I need to worry/budget for this in the near future, or being as by all accounts the car is a good one, is the cam likely to last much longer than that of a rougher one?

Thanks

Theres no hard & fast rules that relate cam to mileage... If it doesn't feel asthmatic at high revs then the cam is probably OK. Get em warm & give em some welly - best test drive of your life.. If owner didn't want to demonstrate that I'd walk away You'll also easily avoid the ones that have got cacked up being used as town cars that way

Unless of course you are after a show pony

My 400 has done 93K and on second clutch but original cam etc...219hp on rolling road completely standard. Don't worry just do it, sounds like a nice example.

As you say V8 Animal, people do say that hence my slight paranoia. Looking at yours, which is looking pretty sweet incidentially, you say you picked it up at 51k - had your cam been changed then?

I'll think you'll find Mr V8 Animal is in one of his slightly sarcastic moods tonight!!

Seeing this pisses me off, mine has 57k and made 187BHP/140
I was hoping it was a worn cam.

Is the myth correct about these cams being soft and needing change then or not?

[V8 Animal]

It cost me dear for those figures
Sorry std 4 litre.
Yes with those figures i would suspect your cam.
Can't think what else it could be according to TVR 240 BHP

Just for interest, what kind of cost are we talking for a standard/improved cam plus fitting?.

I would budget for around a grand.
That's if you want all the other parts that are associated with it replaced at the same time.
That's fitted of course.

Budget £400 for a cam, a duplex chain set and dial, a set of rods and lifters. Could be an idea to change the rockers too, altho that'll cost more!

I presume most do this with the egine in situ..............it looks like it will clear!
