i may have already posted this im not sure but what are some physical features of a b16 b18 b20 so that when you look at the motor you can tell what it is by looking at key features that the other motors dont have i know that b20 will have a b16 head on it to make it vtec but to be honest i just look at the valve cover oh can a b18 or b16 vtec valve cover fit on a b20 thats what i read on youtube?

 

this will tell you what block it is




look on the head, by the exhaust holes and it will tell you what head and year

 

B16 has one kind of valve cover, B18 has two different kinds, B20 has another different kind.

B16:


B18 (LS):


B18 (GSR):

B20:

 

hey thanks alot man oh what does it mean by p72-1 oh and the block info will that say it on my d15b2 in my picture or is some grease covering it? oh and if you can wellfedhobo can you show/tell me the difference between a d15b and like a d16a6 vtec cause there pretty simialr maybe you can show pictures like you and 94civichatchback did?

 

The valve cover for a B18B also looks like this.

 

Block number for a D series is in exactly the same location.

On the D series SOHC VTEC, the spark plug holes are near the exhaust side (front of the car). That's not totally conclusive because there is for example the D16Y7 non-VTEC with spark plug holes in the front. But when the plugs are toward the back like on your D15B2, it's definitely a non-VTEC head.

 

oh ok thanks man umm i actually cannot see my block number and could you maybe show a picture or 2 just to help me along . i will eventually need to know the internals but not now.

 

You might have to wipe the grease and grime away to read your block number.

 

oh ok thaks hey mk378 can you maybe show some pics and i was wondering where i would find where it says d15b2 on my block if i look on the left of the valve cover 2-3 inches below it it looks like it could go there but there is no writing look at my sig pic it may have been removed?

 

where would i have to wipe the grease off?
