Engine demage what hapend???

[Billman]

He is suggesting that certain turbos need an oil restrictor before the oil inlet.

OK, and what kind of a restrictor would be good for these holset turbos??

Sorry, if i go off topic.

I have a restrictor for the k27 turbo wat do you men about #2 is different from the others???????

[AnLe]

I Think I used 2 or 3mm resictor. Thank you Corey for that clarification, that is just what I ment.

Marius: Do you have the block away from the car? I you look closely to the bearing holders on #2 you notice difference, oil feed to top goes there.

if you does not have correct petrolpressure on sylinder 2: read the injektors arent matched,the syl2 have too little fuel,and have the BAD knokkin....or,if the coil/lead/sparkplug are bad,too low spark,you also will have this prob. check out the injektors first....think the syl 2 does not have enough fuel....and there are some engine,who does not like the synt oil.....i does not like it ether.i use the mineral oil always...! i think you should have the pics of the sparkpluggs on the forum....the syl have the light white coluor...or??

Its looks like it may well be an an oil starvation issue.................

I would have ALL the oil galleries in the engine professionally cleaned.....
replace the oil pump and all oil lines......

Have the engine block dipped and cleaned to remove any particle contaminants.....

Then on rebuild with the new parts.....have the engine blueprinted (set to factory tolerances) Or// at least the crank measured for trueness and ground and balanced if required....and ALL bottom end tolerances measured.........

Conrods........measured for trueness and replaced if required.....

Also (II think this has been said also) check the turbo oil inlet size and get a proper restrictor if it bigger than standard....Have turbo checked also........

Also....what are the pistons like??
can you post pictures of them and ALL of their Pistons Crowns (to see what engien tune has been like)



This is JUSt what "I" would do as a start off....

hope this hellps a bit
