corolla turbo Posted January 30, 2012 Share Posted January 30, 2012 (edited) my L28E-head was at local engine builder.they shaved 0,25mm and grinded new valve seats. BUT the removed the camshaft bearing from the head. I read at the engine manueal that these parts doesnt have to be removed?!?! the cam towers are centered with sleeves. so it shold be possilbe to make it like it was before??? someone can tell me tightening torque of the cam towers? i read in this forum, if i shave to much from head, i have to use spacers under the cam towers. but this will mean to remove it. I`am little confused are 0,25mm (0.01") to much without cam tower spacers? do i have to use such once now??

Tony D Posted January 31, 2012 Share Posted January 31, 2012 I think the thinnest spacers are 0.015". The cam towers can be realigned with a mallet and cam installed to check for binding as discussed in several manuals (not the factory one.) You should be able to get them back on there and working just fine. Quote Link to comment Share on other sites More sharing options...
