Engine stop rolling

[Bolin]

Perhaps ask somebody who breaks cars (e.g. seancar) if he could send you some used o-rings or a whole used unit to France.

New o-rings do no appear to be available.

Or could new ones be cut from a sheet of rubber of the correct thickness?

Some people can make them up for you, at a far more reasonable cost!
I would contact a supplier of bearings and seals.

I am not quite sure I understand the problem of low compression on one cylinder, is he talking about bent valves or is he taking about the pressure of the fuel delivery.

Don't forget to test the pumps delivery pressure as well. It is possible that it is too low.

Good to hear you are in one piece!

Hi Kaiser
I ordered and deliver a pump and fuel filter in my garage.
His secretary said now get a pressure of 4 bars without specifying what part was changed. But the car will not start.
Until we have further information on the work that has been done by the mechanic, Can you tell me how does one measure the discharge pressure of the pump?
The mechanic had diagnosed a compression problem on a cylinder . But when I asked the question on which cylinder, he said he must first solve the problem of fuel pressure.
That's where I am

Hi Jymix.

The pressure sounds fine! There is a fuel pressure regulator/moderator on the rear bank. I don't know if they can go faulty, but it might be worth a check.

There is an inertia switch behind the passenger glove box. How they work I'm not sure, I suspect they cut the power to the pump, in which case it can't be that, but it might be still worth pressing the knob on that switch to see if it is operating.

The pressure is simply measured by attaching a manometer/pressure tester to the line.

I am worried why the mechanic can't/won't tell you which cylinder is low on compression. There is no reason to get the fuel system working before he can tell you. So I would disregard his remarks until he comes up with firm evidence.

Why does he suspect the fuel system?

We are back to where we started.
1. If you have compression
2. If you have spark
3. If you have fuel

The engine will start! Which of the above is missing. That is the simple question.

I would get the car tester connected to the OBD socket under the steering wheel and see what fault codes are reported.

I would have a very close look at the mechanic as well!!

And I thought we had this problem sorted!:
But keep your head high. We will! And then we will say, Darn! why didn't we think of that!!!! (that's how it normally goes!)

Hello,

At last news, after my mechanic installed new fuel filter, tried to start the car but in vain. The immobilizer system prevented any normal startup.
And forcing the start, the car gave off a lot of black smoke out the exhaust.
At first, he suspected the distribution and incidentally compression.
For the distribution I told him that this isn't possible because I did it with munitie.
I asked him to check the compression.
Finally, after doing its job for once, he said yesterday that by removing the EXHAUST MANIFOLDS, he discovered that it was filled with sawdust carbon and it is probable that the exhaust are clogged.
This diagnostic seems more logical considering the problems of bent valves and then fuel pressure problems.

Indeed, without the EXHAUST MANIFOLDS, the engine starts like clockwork, however it must be equipped with ball-box support for the noise
The mechanic says it will remove and clean the EXHAUST MANIFOLDS but he advised me to change the whole exhaust system, including catalytic converter.

Hi Jymix!

I must say, I would think your cat might have collapsed or got blocked. I fail to see how sawdust could get into the exhaust??

Anyway. If the engine starts without the exhaust, clearly something is blocked in there. I just for the life of me can't see how sawdust would get in there???

You haven't lost a rag while building the engine, have you?


Anyway. Good, although strange, news!

Glad you are getting somewhere!!

[kaiser]

As for the catalytic converter. Just knock the stuffing out of it!
Unless you need it for for your roadworthy test, the car will go better and use less petrol, if you just knock the filling out of the cat!

(i mean the cat in the exhaust, (god forbid!))

[jymix]

sawdust came perhaps the condensation + extra fuel. Which create micro explosions here and there

I see through you can not believe my exploits.
No sorry, there is no rag left in the engine. lol

Bad news from my garage:
In fact, after applying catalytic, he went to try the car this morning. According to him, everything went well. He could ride over 100 km / h.
Then while driving slowly to 30 km / h behind a truck, the red warning signal began to flash followed by a drop in oil pressure. Time to park on the side of the road, the engine made ​​a noise. He parked and turned off the engine immediately.
And when he trying to restart the car, the engine makes a noise in the lower engine.
According to his diagnostic,
this would be a bearing' problem, even more serious, crankshaft problem ...
For those wondering still questions about the catalyst, many failed ignitions had clogged the two gas filters.

You didn't deserve this!

I feel for you.!

Thank you Kaiser!
It's unfair but that's life ... to each his destiny
