Hello everyone I was wondering if anyone can confirm if the p72 gsr head has the revised style Lost Motion Assemblies that are spring instead of hydraulic from the factory and the year the change was made. Or is this something that they did after they found the Hydraulic were prone to fail at a dealer. Any input would be great.

 

my '99 db8's were hydraulic

 

The modification was done in the S2000's IIRC but either way it was done after B-series engines were out of production.

 

confused OP

theres no hydraulic LMAs on b series they are all spring style

old ones just have the spring inside the case.

 

thanks for the info I think that is the issue with my Gsr my valves are within tolerance but still has tick/tap
