Yeah... Maybe need to service the tappets.
bro, i thought u said that ur engine doesn't have any lifter noise on the mivec engine??? if so, why u need to remove the relief spring valve?
best to check ur engine blueprint if those washers u found are OEM or not to confirm.
IMHO, if after installing washers into the relief valve spring doesn't solve the lifter noise, then there could only be 2 reasons:
1. lifter internal spring has broken
(which i doubt very much due to reasons explained previously)
2. relief valve spring in oil pump has gotten way out of OEM spec, despite installing washers
therefore, as 1st stop guide to solving the problem, suggest to replace entire oil pump to brand new, or find a second-hand oil pump and replace relief valve spring. this option should be cheaper than replacing all lifters. after experimenting myself on this issue, i WILL NOT suggest a lifter change becoz:
i. that's not the problem (unless its broken...which is highly unlikely)
ii. its very expensive to change lifters (ridiculous price to pay to upkeep old cars)
iii. have to go to the root of the problem, which i have found out is the relief valve spring located in the oil pump
CAUTION: DO NOT over-add washers into the relief valve spring assembly as it MAY lead to excessive high pressure in top engine head. For my engine (Mazda B8 - 180), i added 2 standard type washers. This was about 2 years ago, and has totally solved my hydraulic lash adjuster ticking noise :)
good luck to you bro

no lar... Won't blow the oil filter la... It won't be up to that extend. By the time the oil reaches the filter, the pressure already drop dramatically.
aproximately what's the shims' thickness have u added onto the spring?
I have a situation now. One of the water hose to TB came off last week on highway. Engine stalled before I realized. Then waited for ard 15min, I filled in the water n the engine started again. The tappet sound came back. I wonder if it's the heat causes the oil in the tappet to drain due to reduction in viscousity. Or there might be worse possibility. But so Far after driving for a week... No indication of temperature rise n no white smoke. But coil burnt the other day... Coincidence maybe...
oh bro...so sorry i din read this post.....
ic ic ic, i fear you may have a serious problem now
. do you mean water was mixed with engine oil in engine block?????????? if that's the case........then my gosh
...... happened to me before and my engine head was burnt !!!!! sumore you said ur engine stalled ka???? i had to replace my engine head then bro..... ur case sounds very much unfortunately like a case of f**ked lifters dy....
best you immediately change engine oil and re-change every 1000km for a couple of times to thoroughly clean up the engine block.....
i assume u've let ur mechanic check, everything ok with the head????
