Putting cams back in

[Steve GT]

Hi guys

took my head off the other day and had to take cams out to get to the head bolts. just wondering if you can put the cams straight back in roughly how you took them out or if it needs putting in precisely in a certain way and a certain point. dont fancy putting the cams back in putting the engine back in the car and completely ruining the engine because the fuellings all messed up by dodgy cam set up lol

any advice pwease

got the be timed, for safety, it's 100% worth doing. set the engine to TDC for piston 1 and then use the timing marks (be careful not to mix ups the timing marks with the installation marks, they look similar).

[Dean @RW-Developments]

theres usually some white markings on the side of the cam teeth you need to line them up! if youve lined all the timing marks up etc and marked the distributor position you shouldnt need to time it up! it needs to be spot on though

As above bud, to get tdc whip the spark plug out, and i normal put a bar down the spark hole and sit it on the piston, then crank the engine by hand with a 19mm rachet on the crank pully till the bar is at its highest (tdc) then line the timing mark on the crank to the arrow on the cambelt cover, just above the crank pully. Next install the cams making sure the three dots on the inside of the cam gears run in a straight line (horizontaly) this should also put the 4e hole on the cam belt gear in line with the notch on the cam cap closest to the gear, and ta da all timied in, pop the belt back on and tension the belt back up. On a side note tension the cam gear too as it prevents a rattly top end, its easy if u used a service bolt and its a bitch if you didnt, untensioned gears cause no harm just is a tad clicky wen the engine runs let us know if you hit any problems bud.

Also my be worth getting the timing checked by some one with a timing gun as the dizzy can drasticaly alter the timing so is important to check that properly dont just guess however that said the car can be driven to a garage etc to be checked, it wont blow up if the dizzy is out

[Steve GT]

hmmmm might play it safe and get someone who knows what there doing to do it then lol

[TheStarletGT]

I believe this will be a disaster in the making.

[Steve GT]

why?

[Socks]

if u get it wrong, you'll bend your valves....

so yeh id get someone to do it! nick manning in town id trust with my life for that sorta thing!

[Steve GT]

i know i aint doing it myself

just wondered what the disaster in the making comment was about lol

[ep_brad]

im 99% sure the 4efte is a non contact engine so you wouldnt smash your valves up.

im 99% sure the 4efte is a non contact engine so you wouldnt smash your valves up.

id be VERY suprised if it was a non contact!

[Steve GT]

Thanks for that ^^^

going to play it safe and go see a good mechanic on here who knows the engine well and get him to do it for me though

[Steve GT]

just got off the phone with chris he said its easy to do and has just talked me through it all so going to do it at home next week

What a guy though knows a hell of a lot lol

[cazzac2222]

Have you looked at the videos over on TGTT, shorty pointed me in that direction as i need to do my timing and was misunderstanding what people was saying without pics, im pritty much sure it will tell you step by step how to do it and all the torque settings aswell

Heres the link:

[Steve GT]

thanks for that matey always good to see vids too

[cazzac2222]

No worries dude, yeah i just couldnt understand what people was telling me to do without seeing pics or videos so shorty pointed me in that direction, so getting it done tonight

[Steve GT]

got to get my head skimmed, wait for some new head bolts to arrive then have a go myself ;)

let me know if you have any problems or if its easy just so i know

[Bluebear]

Chris as in Nastyrash? He knows a stupid amount about engines, glad to have him reasonably local to me ;)

[Steve GT]

yep thats the guy

did u put the service bolt in the cam gear when u took the cams out? if not you'll have to put one in or u will have a rattley head.

[TheStarletGT]

I doubt that ^ very much. I had no clue about that so called serice bolt thingy and i dont have a noisy head.

ok mate, well tell me why toyota say u need to do it? its ment to tension the inlet cam gear. i forgot to put it in when i put my cams in and it was noisy, took the cams out again, put the service bolt in (with great difficulty lol) put the cam in and it was fine.

Personally i wouldnt leave it un tentioned.

[mk1kurt]

no i didnt but i'll sort it out when it comes to rebuilding it

cheers kurt
