Thanks. Will check it out.

Or can be carbon buildup in intae valves?? Cy1 and Cy3

 

Hello everyone. I just got answer from mechanic. They said that cylinder 3 has low compression. It would be a couple $$$$ to open and inspect it.

Wha is the best suggestions for me to do it?

 

what were the numbers?
where is the compressed air leaking out of?

take it to another shop for a second opinion.

 

I didn’t ask about number. They just told me cy3 low compression and need to open to inspect. They just wait for my answer

 

in order to make an informed decision, you have to know the numbers and which cyl. you dont want to pay money specially close to 1k for inspection and then be forced to either pay to repair, another 2k or buy another engine for 3k +

ask them all the questions until you're satisfied. ask them to open the valve cover and see what is going on.

 

Just talked with the owner of the shop. He said cylinder 3 has 50 compression. they don’t know exactly till they open the head. And he told me that could be something dropped down into spark plugs hole and damage valve, piston or rings.

 

Let them open the valve cover first and notate the valves or anything weird.

 

They can also put a scope through the spark plug hole; no need to pull the head quite yet.

 

They wil charge just open the valve cover.... thats pricy

 

I hope they would do that.

 

 

Will go to shop tomorrow. I live in Boston MA. Here is hard to find Mini mechanic except Mini Cooper dealer:(

 

Here is a site that lists independent MINI shops all over the country.

Thanks so much. I found one 5 miles away from my home. What do you think?? Can I drive it to shop with cylinder 3 low compression (misfire) ?

 

 

will see. just wait for the exactly issue tomorrow

 

You could sign up for AAA for about a hundred bucks and get a tow when your membership kicks in. With AAA you get four tows a year for the cost of a membership.

 

The shop just keeps saying I need a new engine !! Lol

 

tell them, "that's what she said" lol

take your car out from there.

 

Yes. Will take it away from the terrible shop

 

Anyone know how to clean up carbon buildup in intake valve??need to have specific spray?

 

Take the intake manifold off and walnut blast the valves. the only way to clean the valves is to mechanically clean them. Some have done it with chemical carbon removers, like seafoam, but they also had to use a wire brush and a dental pick to get the carbon off the valves.

 

Can I do it by myself? Or use brake cleaner or throttle body cleaner to clean it?

 

There are some very good tutorials right here.

Here is one to get you started.
