Xu10J4Rs Hydraulic Lifters

[sale_gti6 2 1 Cars]

I need advice. Several hydraulic lifters knocks on my Gti 6 engine and I'm plan to replace them. Also, I have hydraulic lifters from my previous Xu10j4 S16 engine,and I was wondering if S16 hydraulic lifters fits on Gti 6??? If they fits, I do not have to buy new lifters...

Yes, identical bore but slightly different length. I would use the S16 lifters (reco'd) if I had no RS lifters.

I thought so, but I was not sure. thank you

I check timing and it's OK. When engine is cold, nothing knocks. Suspect hidraulic lifter...

Any idea if the j4r and j4rs lifters are the same or if the J4 lifters will fit a J4r?

Also are the xu7 lifters/followers/buckets the same?

 

ive looked at some eBay listings and it shows pretty much all XU 16v buckets and lifters are the same? 

[welshpug 1,657]

they're all the same o.d, I think there are differing part numbers but they look to be identical, Peter said they would fit above.

 

its the EW engines that went smaller o.d to make the valve train lighter.

infact I have all 3 types, maybe I should take them all apart

Please do and report back. R and RS lifters are definitely different part numbers but I can't see how the relationship between valve tip and base circle diameter is any different.

[calvinhorse 870]

Yes please have a look

 

my predicament is I have a j4r head with no lifters but I have a xu7 head on the way and about a million j4 heads

XU7 and R: 0942 45

RS: 0942 31

Is that the internal hydraulic part?

[petert 586]

Nope. The whole thing.
