Oil pressure

The chain I was given by the REPCO store is the corect chain but it is to long the old one had broken due to a joiner link in the chain and I was told buy 3 machinacs that it would happen again if I was to shorten it by removing links out of chain I had started my ute and had it runing for no more than 5 min and I still hav an oil light on dash board and thr is the corect amount of oil in engine

I have just dubble checked and all belts r tight al wireing is conected the oil pump was working before the balance shaft chain broke is there an internal oil pump?

Thats not my model of engine the pressure relief valve is on top and horozontal of crank shaft pully and there is a spacer that fits inside the iner rotor around crankshaft

2.6 is wht all engine stamp plates say

Sory mate u prob got beta things to do thn answer my ******* questions but can u tell me whr the rotor button needs to be when al other timing marks are lined up and also whr the oil presure sender is thankyou

Al the advice for u was great I thank you just a few things that I have to fix eg a slight vibration from passenger side balance shaft and a few oil leaks that I didnt seal properly again thank you

Have oil pressure now and yea oil leaks just whr I havnt seald it properly I didnt use a gasget I used the goo n yea I think thats all iv done with the vibration is just havnt put the balance shaft in the right position
