Replacing Valve lifters

[FastDagda]

Hi all, recently purchased a 98' model that had a lifter rattle at 2.5k rpm. Car still drives well so I added an oil treatment to see if it would free up the hydraulic lifters. It has improved the situation but I've gone all in and decided to replace the whole lot.

While I'm doing this I will also do the timing belt and tensioners etc, I am a fairly capable motor engineer so this is no big deal, what I'm wondering is whether to go the whole hog and do the water pump and crank/cam seals at the same time? Is the water pump a major issue? It seems fine at the moment.

Any advice would be greatly appreciated.....

OK, thanks for that, so how do you explain a rattle at certain rpm? Surely if it was shims it would be constant? Car drives sweet apart from the 2500 rpm rattle!

It's a cam noise, rattle/rumble from the top end. Have tried to strip engine today but only succeeded in smashing my arms trying to undo the crankshaft bolt. Have put it back together and will be driving the piece of st to the scrapyard asap.

Really confused by the community that own MX5's, people tell you that my car doesn't have hydraulic valve lifters yet will sell you replacements. Lesson learnt in my case, expensive lesson too!

It's a MK2
