@Varun:I think that is the margin for heat damage.The head must have warped a little.Not perfectly flat.
Yeah dude you can check the prices for a used head, it will be helpful for him.I think its a 4valve mpfi head.he said his car was a 2006 zen lxi.

Correct me if I am wrong @surfer
Ps:There is an oil strainer in the engine, ask them to clean it thoroughly.

Hi get your head faced if faced too much try double head gasket to retain the compression try this before going for a new head
Also do you use coolant or plain water in radiator? in any case get the thermostat "VALVE" checked along with radiator fan.

@nanhi99:What if the thermostat valve is removed?

Re: Zen is Stalling Frequently - Help Required.

removing of valve will result in late heating of engine resulting in damage to engine in long run. In morning when you start the vehicle temperature needle moves to half in very short time after removal of valve it takes very long time to reach normal operating temperature still does not reach that level for mpfi vehicles it is very necessary to keep temp at bay

Re: Zen is Stalling Frequently - Help Required.

over a period of time thermostat valve gets rusted resulting in improper function of cooling system

Re: Zen is Stalling Frequently - Help Required.

When you remove the thermostat valve the engine takes a lot longer to reach operating temperature.

But a lot of garages just remove the thermostat valve.

Re: Zen is Stalling Frequently - Help Required.

Removing thermostat valve is not at all advisable. The engine should be kept in stock condition, atleast. Removal of thermostat valve is detrimental to the engine. Components can be removed without getting any visible affect to the engine. But thats not the way it is.

I know its not advisable, I bet if a lot of people checked they would find theirs missing as well.

A garage guy told me that a lot of thermostats are removed during services.

Re: Zen is Stalling Frequently - Help Required.

yo can check the valve & if necessary get it replaced
what about your head?

 

[nanhi99]

Re: Zen is Stalling Frequently - Help Required.

if you are changing the valves then replace all the tappet adjusting bolts also.
