I solved With the replacement of all the castelletto of the tappets,the car had broken earlier in the distribution chain, and the camshafts had slightly "rotated" offsetting all. The owner claimed not to have ever made interventions to the engine though...never starli feel it!!!
Ok problem solved
hello joseph, mi to fond your problem.Originally Written by giuseppe89
I am on your shoulders I bring 20 years of experience in computer science and electronic engineering and from 2013 I have my own business
I learned that the defects and the history of his own unit/etc that was said by the customer for the 90% not true!
when they are improper even worse!....this is the end of thinking that we, the repairers, electronics/mechanical etc we are poor idiots that there accogiamo of the mess combined from the other, pesnando to our compassion
and carrying out other flaws as there are with the same quote.
when ever one breaks the distribution, are not aware of it, and bring the car in those conditions.
them and broken chain,a damaged camshaft, valves, rebuilt the distribution, hoping to go and maybe for a short time and also went well and then get worse.
I smell so much of the work done by a friend that if he intends to.
surely in this your adventure today I learned something about the other engine.
The engine 1.3 mjt when he breaks the chain rarely piegha the valves but it breaks the rockers and not the cam-strung ,trees are made to melt! on this they turned the cam is mollata the distribution side of the pump that has two gears with bolts, one right and one left made for mollarsi in the case of locking
The important thing is you fixed :-)

Cele if it were as you say the tips deĺla phase would not be entered, and instead wore perfectly...have given torsonialmente at some point on the axis, but the phase was correct with the kit setup phase...Then these cars if they are galore but one thing I had never happened
If the test leads to come in properly could not be dropped, however, and too strange a twist breaks the rockers before twist, or the spring gear

hello cele excuse I would understand, giuspeppe, however, says he has found of the valves damaged, if I'm not mistaken, that did not fit well in the seat.
I don't know the multijet but I imagine a hypothetical speed of 80km/h, how likely is it that you break when all the valves are closed?
always that the headboard is not as high as the old fire petrol that can't get to the point of touching the valve, and tea and the other I find it a brilliant thing!
in any case, I was always told by many experts that in case of breaking belt or chain distribuzine, and always better to raise the head, even though there are those lucky cases where it is not happened anything.
and with a dual-axis cam as we put it, that I know a 1.5 dci renault.
and impossible to know at what time it breaks, and that state remains the engine.
I do it on the mail, I went to see 2 days ago a seat 1.9 TDi fr sport for me, the price was almost feasible, but with the distribution route.
the owner did put the belt and start again, but with a metallic noise that seem to be giving mazzettate on the pistons.
not taken only because the type he wanted too much money and imagining the worst, I had to put another engine.
then I would like to understand how many possibilities there are that it doesn't happen a casino stratospheric if it breaks, the distribution of an engine.
Then we see to clarify the mjt as many other modern engines in the event of a break distribution, break rocker arms, then in the worst case even if it yields the rocker bends the valve , alcunimotori type, the psa, in addition to break the rockers is to turn the cams in the axis, but here, too, can bend for the vag group at least as far as the 1.9 and the 2.0 tdi ones break the valves then there are cases that luck nothing happens
am a mechanic by profession and in my workshop I often have to remove the head on the car that break the belt, but mjt for now I have removed 2 out of 10 car

in fact, and what I was saying and I wanted to understand on the multijet.
now, and clearer, in fact I wanted to understand this thing who does that every day or often
Guys the car in question had broken the chain in the past and was all the time sheltered in a bad way,and from then on started to 3 cylinders,he smoked and turned round only when the engine is warm or almost...since the customer said that you have not done anything over the dealer service the accounts did not return seeing the timing case sealed with mastic that is not original...not having the correct compression on a cylinder was disassembled ls tested and controlled...grinding, claimed that some valves do not close perfectly, and thus it was revised...re-assembling everything, but to present the same problem.Talking with a friend, colleague speaks to me of a similar case where after the breaking of the chain had had this problem to the camshafts,now I can't say where yields but replacing the whole car was perfectly 4-cylinder
