R50/53 Running lean....
A valve job at a machine shop puts a precise bevel on the valve and seat surfaces which is superior to what you can do with lapping. After you lap the valves a few times, you will have a groove in the seat which is not desirable, so you'll have to have them ground and or replaced.


I've been changing my own oil, tires, spark plugs, wires, 1 coil and a couple other small things. Not quite ready to tackle taking engines apart yet but I would love to be able to do it some day!
I'm female

my machine shop charges 130 to resurface and pressure check the head after you lap in the valves and why is it rediculous to do 1 valve that's like replacing all 4 tires because one got a nail in it.
No worries! How's one to know. We're all just a screen name and an avatar around here!
I agree with your advise. In your opinion do you think it's worth doing for a car this old with high mileage?
Cheers

Yes the body and interior are still really nice. I'm the second owner....it's paid off. I haven't put too much money into it nor have I had to replace much. I know my only concern is wondering if its at the point in its life where a lot of things start going at once specially since I haven't had to replace a ton of things. My main concern in the tranny. The automatics have a bad rap. Mine seems ok at the moment. Are there any tests that can be done to the tranny?

IF you do the head, have them change the supercharger oil and look for any issues.
This all is of course just my 2 cents. Post some pics.
Thanks for your 2 cents. It's helpful to have other opinions specially from other drivers.
I think I have the CVT transmission as mine is an automatic. Also its just the base model...no supercharger:(

Woah I didn't think you would attack me so openly look I don't remember the name of the shop to me it's left on this street and the third building on the left. A friend of mine is actually a MINI certified mechanic who has moved on to start his own business and has done many of these all the info I gave was straight from him so get a quote from a machine shop and look up the cost of a head.
The mechanic called with his labor quote today(I plan to provide all necessary parts).
He quoted me 14 hours using my existing head and 13.5 if I got a refurbished one. Thats what he said his magic book said.
I don't know much....ok...anything...about taking engines apart but these numbers seem high. Is it?
I mentioned the refurbished head to him and he said that what him and the machine shop will be doing is essentially refurbishing it....
The machine shop part is $140 plus tax
All this is the price to just replace the valves that are burnt....I mentioned replacing them all and he said he thought it wasn't necessary.
The car isn't worth much anymore...I wonder if I should just drive it as is until I really kill it! It still has lots of power it just misfires every now and then

I might go get a second opinion/quote elsewhere just to see.
When I did mine in Nov 2012, it cost $2100 parts(new head) and labor. They would not do only one. They felt the same way I did about others would fail later, so why not do it right the 1st time.
So half hour difference in what then? machining the head only takes half hour?

I'm not sure what the half hour difference is.
Yeah that could be interesting. Might need a new thread on it as i'm sure it would get a lot of attention.

Some shops go by the book on time and others go by how long it actually takes them. Is there a local MINI club where you are they would be the best bet for finding a good mechanic. If one axel or hub bearing goes bad most would say it is unnecessary to change all the others even if they all have the same mileage.
+1 on do them all, the major expense here is removal & install labor, why risk having to do it again in the near future.
And even with a "justa" as far as the motor goes you're still looking at prob. getting 200k (320 km) out of the bottom end. (but definately do a good visual on the cylinder walls while the head's off.)

You must be from the same old school of thought as me.

Oh yea you are so right
Let him do it himself.
