Rb25 Rookie timing mistake , damaged ?

[Frozengrip]

Well guys yes they are f**ked ! Lol but good thing just got em back from machine shop and all good !

 

now just gotta set everything to tdc, mount it, torque and we're good!(:

[Frozengrip]

Ok guys so , cams are set at tdc : #1 lobes pointing away from lifters, and winded Pistons clockwise from my 10mm to tdc with head put on. 

Now question I have is #6 valves are open and # 6 piston is at tdc? This right ?

That's called overlap. Top of exhaust stroke, beginning of induction stroke, both valves are slightly open. Exhaust is closing, inlet it opening.

Ah got it , so it’s correct as it is yes ?

i know when I set the timing ... the right time this time that things should align probably 

[GTSBoy]

Yes it is correct. Whenever a cylinder is on compression/firing stroke (ie, #1 in this case) then the other cylinder that is also at TDC will be on the exhaust/induction overlap.

Why did you put the cams back in the head before bolting the head on? Surely they came out because of all the rust?

Thank you for being so informative gtst, this is awesome ! So seems like I’m on the right path and all is good!

 

@ben that’s how I got them back from the shop , but I didn’t torque head down yet. Just mocking everything up and make sure it’s all ok.

now just gotta wait for my days off to get it all assembled and done!

Yes, but they still look concerning. Viz the circled examples.....

All of this looks very unimpressive. Got some closeups?

Ohhhh they put assembly lube on them ! Yeah kinda looks like shit from that close up but I can assure all Rust is of and they lubed all lobes!

thanks for the heads up tho gtst ! You’ve been of upmost help

[Frozengrip]

Set everything to time on the cams and crank. And get everything bolted down , now time to put on belt and torque the cam bolts after. 

Thank you everyone for the much appreciated help! I think this time around I got things right lol
