worn cam bearings

Hi Newbie here,

I have an '89 clipper with 1800 carb engine.  The cam bearings are worn and the oil light starts flashing after warm up.  Are heads from early MK2 1800 engines compatible and does it matter if the head was off injection model?

Please help :dontknow:

any mk1/2 1800 head would fit, injection head + cam would be a nice upgrade only thing if you are using the pierburg carb still is you need to drill a hole for the coolant channel.
dead easy to do as head is alu, match angle/size of hole with your old head, drill till you hit the coolant chanel
If you have a webber this step is not required, just need to block off the coolant hose coming off the metal pipe round engine.

last thing is you meed to block the injector holes, either leave the injectors in or unwind the inserts and drop a penny down each hole.

edit: earlier heads will have solid lifters which isnt an issue except you need to make sure you get the right solid lifter cam to match.  also early k-jet inj heads have an air feed where you need to coolant channel to be, so would be no good to you.

Cam bearings worn ? Never seen a worn one causing low oil pressure . Bottom end worn  ?  Yes .

yep 100% it will cause low pressure, but only at the head i.e. where the low pressure sender is on an 8v.  had exactly this on a 'rebuilt and flowed' mk2 gti head, low oil pressure when hot at the head (enough to bring on dash warning light!) but pressure perfect when sensor moved to oil filter housing (I had a VDO pressure gauge, using a 2 pole sensor). in addition the head I took off had perfect oil pressure, problem started the day I fitted the head.  even put a new oil pump in 'just in case' same problem.  Head off again and cam caps were indeed trashed!
