What are your thoughts about fitting a new hydraulic lifter on an old cam? 3.5 carb.
I've got the intake off at the moment to fix oil leaks at the front and rear of the block. Someones been in there before and used no sealant in the block corners. While I'm in there I was wondering wether to replace a lazy lifter. It sometimes ticks away on startup for a minute or two then pumps up.
I'm aware you can get an issue with fitting new to old in that if it doesn't start spinning correctly and bedding into the cam it will flatten the lobe. The cam actually looks very very good at the moment.
If I do fit it I'll run it up to 2000rpm straight away to bed it in. Worth the risk?
The other thing I did think about trying is swapping the lifter internals old for new and keeping the body. Hence keeping the wear pattern. Not sure if anyones tried this?
