Valve seat recession

[johnny_h]

anyone ever actually suffered from this? I was about to send of my head to have hardened seats fitted then a geezer at the pub said save yourself 300 squid. What's the score? opinions plz

After 3 years of lead free abuse my valve seats are showing no signs of wear.

 

I'd say if its a weekend kind of car and your not going to clock 100k in the next few years then save your money, I am

Whats the worse that can happen, in many years time they start to recess, then you'll need to get hardened seats.

 

Don't do today what you can leave 'til tomorow

i was talkin to some old numpty at a show he claimed if you stick to 40mph you will be fine on unleaded

I stick a bit of Millers VSP in with Optimax. Got a bit of octane booster and deffo no sign of VSR. Never been brave enough not to put it in + it likes the octane!

 

Or do the Mr Sam. But mind the 30 mph cameras!

you dont need hardened seats may just need recutting and check valves for wear

[Rick]

a new gasket and a quids worth of cutting paste....

 

cheaper id say

Hook, line and indeed sinker.

You can't recut if theres no metal left to cut into

TBH if they all resessed at once it'd save the engeneering company cutting out the old seats to fit the hardened ones in

the harder you drive the quicker it will happen either way it will happen enventually
