Identifying 197 cams

[jon_r]

Is there a sure fire way to tell the difference between 172 and 197 cams?

I just want to check the cams I've got are actually from a 197.

The numbers I can make out are (though its really hard to read them):

Exhaust:
F4r r194
243 23h23

Inlet:
F4r a 318
E06 11h45

​Cheers

I'm certain mine had 822 or something on them.

Offer them up to a set of 172 cams - You'll visibly see the differences in the lobes. The 197 cams have longer duration and they're also more advanced from what I remember.

Will do, thanks. Need to get them out of the engine first to compare!

197 cams should have a timing wheel (4 teeth) on the inlet cam.
I've got a pair I bought that someone has removed the timing wheel so it's useless for what i wanted (actually going in a 197)

^got a spare catcams timing wheel bit if you need it?

 

[Dan519]

that could be useful if it'll fit on a standard cam actually.

i'll give it a go after my lunch

I know this is a terrible picture, but the thing towards the right hand side?

I need to remove that then? I know thats a stupid question, i've not paid much attention recently.

 

[Dan519]

no need to remove it, just someone had on mine annoyingly

Cheers Dan.

I've got a rocker cover leak and these, along with some Megane injectors and a map, will clearly fix it.

I take it you know what setting to dial the 197 cams in as then?

did you ever dig this out?

 

[jon_r]

Sadly these are still sat in the boxes. I need to buy another timing horseshoe and get it bent.

I'll do you a part ex on some Pipers if you want, could do with a second set to get reprofiled as exchange units for the 197, and you'd see more noticable gains
