...block when you put an engine together?

Basically this wasnt done when my engine went back together

The bottom end was bought 2nd hand and had done 1600miles before the car was rear ended. It had had a full rebuild and should be sweet. Now when in my car and engine is started theres a horrible tappety/chappy noise coming from the engine. I'd had a few people have a listen and they werent sure if it was bottom end or top.

Last night i got the car recovered to a garage where 2 guys are gonna fix the car. Having started it and listened they didnt think it was a bottom end issue. They felt round the back of the block and said that if there was something not right they'd feel it on the block? They were thinking its summat in the middle. So then i remembered about the lack of wire in the wire rings and they wonder if that could be causing the problem. Does anyone have experience of not using the wire? Can it cause a problem with the seal round the bore?

if the other cylinders have the wire in them and the middel ones dont they wount seal 100% but if all the wires from the block was removed and the gasket laid on top it can still bite into the grove with out the wire ..

so is ither with the wire or with out not pix and mix

ither way the sound my not be relaed to the gaske it may be a littel end noise fron the con rod that make a rattel sound that sounds like its coming from the head

Lambchop

thats fine then i have none people to do this with good results the fireing ring on the head gasket will still crush the same but were the grove is cut it will simply indent it self there and lock it self when you take it of you will kind of see

dont say that as i need to find a problem

why didnt you put wire in?

Turbosystems

iTrader: (5)

yes why didn't you chop

Lambchop

iTrader: (1)

because im a clueless dipshit. whats steve's problem?

he said it as if he meant to leave it out hence me asking why that choice

Turbosystems

iTrader: (5)

if a block is wire rung and we are rebuilding it using a metal multilayer wrc gasket we re machine the block so that the rings are flush, simple, but then i am a clever dick

Simple maybe, but surely thats going to have your piston tops protruding another 20thou unless you start skimming them as well, which will then move the top ring further up, so you still have potential problems.

Turbosystems

iTrader: (5)

read what i wrote chip you have assumed that we have skimmed the block face, what we actually do is machine the ring groove deeper in the block face until the ring is flush with the face

No Chip you misunderstand...........the wire ring grooves are machined deeper...........you do not machine the block face (deck).

EDITED: Damn tooooo slow

Just posted on your other thread Chops

When i had a listen it deffo sounded like a small end. Couldnt pin point it as the tapping noise was from the centre of the engine.

Std or Grp-A gasket will be fine without rings in the block but if you are going for a multi layer WRC jobbie then do as above

Melted piston

vroooom ptssssh

Who put it together chop? has it done any miles?

Hard to tell what it is without hearing it, sure all will be revealed when its taken apart! atleast for the price of some gaskets and head bolts you'll know for certain!

i do actually worry when i post shit on here

maybe one day i can treat you to a trip to germany and back in 1 piece in the same vehicle

Dannn

I don't think the wire rung stuff etc has caused a melted piston. I think for whatever reason it has melted a piston and that is the noise you can hear. Heard a few engines including my own which sound like a top end noise/rattle/tap etc only to turn out to be a melted piston. Have you got it apart yet ?

Has it actually been on the road in your possesion chop ??

Just had the grooves cut into the block face so the rings on the headgasket could bite down into them.
Done about 25000 miles like it as well

we're talking 2 DIFFERENT engines mate.

"original" engine in the car melted a piston. NONE of that is currently in the car.

the "new" bottom end is the only 1 with wire ringing. We put it together with a "new" head and it makes a horrible noise. Its only run for 10mins total maybe to check the problem. the sump is off it and there are light marks on the shells. engine out and head off tonight
