6 bolt vs. 7 bolt [merged] 6bolt 7bolt 6-bolt 7-bolt six bolt seven bolt

[asdfzxc]

All 6 bolt vs. 7 bolt threads are merged here.
How do I tell if I have a 6 bolt or a 7 bolt?
Will x part from a 6 bolt fit a 7 bolt?
Will x part from a 7 bolt fit a 6 bolt?
Which one is better?
How do I swap my x bolt for an x bolt?

What is the difference between 6-bolt and 7-bolt engines (aside from the obvious - 6 vs. 7 bolts connecting the flywheel )

Is there an advantage over either of the two engines?

Thanks,

-Mike

buahahah.........dont feel so bad, i only drove mine like 470 miles or so when the timingbelt did the same as yours...
my valves where bent and one was missing half of it.
stupid timing belt decided to take a break while i was doing bout 80 mph on 3rd trying to beat my little brothers integra ( ithink i won):laugh:

I own a 90 laser fwd turbo. The drivetrain is stock(for now). Does anyone know for sure if this is a 6 bolt or 7?

Also what are the advantages of using 2g pistons in a 1g motor, and what has to be done to make this work?

 

[L2RTSiAWD]

Well if the motor has never been pulled it's a 6-bolt.

the way to tell if u have a 6 or 7 bolt engine is to look at the exausht manifold studs, if u have a 6 bolt they will all be 8mm studs all around. if u have a stock head. If u have a seven bolt their will be two 10mm studs on the far ends of the manifold and the rest will be 8mm studs, you all so can tell by the size of the oil pickup too, Looking at the pan is defintely not a good way to tell.

Go to the dealer and give them your VIN and they can tell you. Or you can pull the tranny and clutch and look at the flywheel.....your choice.

 

[talonturbotsi94]

well im about to pull of my head to change the headgasket so ill go ahead and pull off the tranny while im at it and look

 

[Eliminat0r]

ok well im looknig at this 95 tsi awd and it says it has a built by cummins 4g63 in it designed to noit get cw so im wondering if it could be a 6bolt some poeple say you can tell by the cas so i have included two pics of the engine.

let me know if i go look at it ill also check the flywheel.

 

[SpeedFreak03]

Sorry I dont know how to tell buy the cas, but how are you gonna look at the flywheel? Is he gonna let you drop the tranny?

 

[Eliminat0r]

he wont know if i drop it or not. i would look after i bought it

 

[dave99gst]

im guessing thats a stock 2g -- judging from the intake mani and the fact that its got a stock BOV i/c pipeing. it looks pretty much un-touched sept for the intake

 

[Eliminat0r]

so hes lieing about the fully built engine by cummins part or could it be that he just had cummins build his 7 bolt

 

[Eliminat0r]

actually now that i think about it those pics are probbaly before he had the engine done because theyre old, and the engine only has 1,000 miles on it and he just put it up for sale soim guessing i need newer pics totell ill ask him to e-mail me some.

 

[spoolinawddsm]

we are able to tell if its a 6 or 7bolt by looking at the valve cover

 

[Eliminat0r]

someone said if it has a cas on the pass side of valve cover its a 6 bolt or a later 7 bolt, im just trying to figure out if this guy is lieing about the swap before i drive two hours and find out he is and then have to whoop his ass.

 

[blcknspo0ln]

go to vfaq.. learn how to look at the oil pan and get a hold of a pic

 

[jamiesibley]

from the pictures there I didn't see a cas on the side of the head, that means its a 95 or 96 7 bolt engine that has the cas/cam sensor down on the crankshaft. Thoes pictures are definatly from a completly stock motor.
