Engine warm


Hi all


Hi jalalski.

I restored my car engine 6 mount ago and oil consumption solved (if forum is accept i will make a gif animation for my car engine problem),but i have a new problem now.When the engine is hot it will not start work maybe 10 seconds if engine is cold then it take start normally.And my car engine is always too warm approximately: 30 km from later.Gas pedal is very hard and engine power very less than cold. (Heater indicator always appear normal). What can be? I went to the some service but everyone said diffrent things.

Sincerely...Thank you.

Hi mate,

It could be a faulty crank and/or cam position sensor (or both). Check the threads HERE on this subject.

As for car engine always too warm, well yes, it gets pretty hot in the engine bay, but as long as the temperature needle is normal, it's not a concern.

Re: Engine warm


When you mention engine power is less when engine is warm than when it is cold - it is normal for you to think this is happening for a few reasons (I'll try not to be too technical).

1. As the engine idle speed is higher when it is cold, so it gets to higher revs slightly sooner than after it has warmed up and the idle revs have dropped to normal.

2. Te air is cold and more dense, allowing for better combustion, making it feel like it has more power.


The only thing I can think about the pedal being hard - check that the floor mat isn't stuck underneath the back of it.

I wouldn't be worried about the engine temperature unless the needle goes near or into the red zone. Mine normally stays about half-way up the scale a few minutes after starting the engine.

Re: Engine warm


Sounds like when the engine was replaced that the intake system may have been assembled with a gasket missing so there is an air leak.

When the engine is cold, the gap will be small so the leak will be small but as the engine warms up then the gap could increase and more air enter the intake system without being registered by the air sensor. This would cause the engine to run lean and starved of fuel so it would be harder to start and feel under powered when running. The further you put your foot on the accelerator, the more manifold vacuum created and so more air leakage.

Have a mechanic check all intake joints after the air flow sensor.
