Hey, I just picked up an engine privately from a for sale thread in a local forum.

Once I got it home I became suspicious that something funny had been pulled. The engine is supposed to be a complete B16B with a 2001 Integra GSR tranny.

First thing that made me say wait... was that it is obvious to me the valve cover was painted red from its previous colour, black. This is evident with some red dripping marks over black on some hard to reach areas. If B16b's come with a black valve cover I was unaware.

So please help me, I am thinking its possible my head is actually a B16A with a B16B block!

Attached are pictures of any stamps I could find on the engine to help someone who knows more identify it.

Thanks!!

That`s a B16B alright. As for the rocker cover beeing black, no issues since it`s interchangeable for B16A,B16B,B18C engines. And i can see that your oil cap has also been swapped. R engine oil caps are chrome. What does the stamp on the tranny say?
 
Lol I cant find anything.

As for the valve cover, I'm just thinking why change the original one to this one that's also in bad shape.

how are you sure the head is B16B? the PR3-1 stamp?
 
The block is stamped B16B, so the block is definitely a B16B, but head however doesn't have a B16B stamp.....I'm not sure how you differentiate between EK9 heads and other b-series heads???? But the B16B stamp doesn't relate to the head!
 
You`re right, but it would be too far, to have a 16a head. Let`s not frighten ehmis and be optimistic about it.
 
not sure about the head being type r. its got a b16a intake manifold on it. take the valve cover off and see if u got dual valve springs on your intake and exhaust sides(b16a heads only have dual springs on the intake side). as for the block anyone can tamper with the stamping on the front. take a pic of the bottom of the oil pan. if the pan has a p72 stamp on it your good.

I'm not trying to frighten him dude :)

Just trying to help him figure out whether the guy has pulled something fishy! It's pretty unlikely that the head is not an EK9 head with EK9 valvetrain, but it's worth finding out in my opinion! Otherwise, who knows what cams etc are in there!

It could run pretty bad if it's a stock B16A head and an EK9 ecu!

Did you see the engine running before you bought it Ehmis?!
 
Lol well I got it for cheap, the valve cover is black.

I'm meeting up with the guy in somehting like 4 days, so I have the opportunity to confront him about it.

I know the block is B16B, but if the head is b16a, it kinda defeats the point of getting a B16B.

So if anyone knows a sure fire way to differ a B16B head form a B16A, I would like to know.

Dont have to spare my feeling or anything lol.
 
i also just noticed what looks like a oil pressure switch sensor on your head which never came on jdm cars. though i cant tell for sure with those pics but your head is looking more like a b16a head.
edit
also looks like theres a sensor on top of the fuel rail with that red vaccum hose and black cylinder thats suppose to go to the evap canister on the fire wall. this def did not come on any r and came factory on usdm civic si's.
u also have the rhd throttle cable bracket on the valve cover.this swap looks like it was pieced together with all different stuff.

I would take the valve cover off if I were you mate!

And do what sek2dts@aol.com says!! Plenty of people out there who stamp B16B/B18C on different blocks :nerv:

The black valve cover and B16A intake manifold just raise suspicion!
 
Yeah it was running, I took it for a test drive in his SIR.

It didn't pull as hard as I expected it to, but he was running an SIR ECU with it, I have the type R.

That was the only weird thing I noticed other than a burning smell the second time I test drove it, but drove it hard.

ALSO, now I have i home i noticed the spark wires have some oil on them. That shouldn't be right!?

So luckily I have a crane here next to the engine.

I lifted the engine up and there is a stamp that says p72 on the oil pan. So I buy that its a B16B block for now. ( I posted a picture of it in the top on the thread )

SO! Currently I don't have a ratchet that fits the valve cover bolt sizes. As soon as I do, I just take it off the valve cover and I will know for sure if it is a B16B head if it has dual valve springs its that simple?

yup there should be 2 springs(inner and outer) for each valve. if the exhaust side only has 1 spring per valve its almost definite u have a b16a head.
 
as said before...thats a b16a intake mani on that engine!

i would guess its a "jap spec" b16a hence the running with a SIR ecu,but
i could be wrong!

bit of a "pick n mix" if its a b16b with all the different parts !

hope it comes clearer for you soon pal :nice:
 
I would concur thats a b16a2 head and intake. So looks like your going to be missing the cams that come with the b16b head unless they did a swap.
 
Okay i will take the valve cover off ASAP.

It just comes right off, no special steps to avoid wrecking something? I wouldn't think there is, but just making sure. before I go ahead and take it off.
