Cam Installation Help

[93H22A]

Ok here's the situation
my friend installed GUDE cams with AEM sprockets on his prelude and now the engine is really loud and makes clicking noises.
i have no idea what that can be.. he checked the TDC and the adjustments but it still behaves the same..
can anyone help?
thanks SRO members...

By the way his car is a 94 Prelude Si

so the timing is correct...and the valve clearances are fine
you may have busted a valve spring

hmm, why he install a CAMSHAFT by himself?
some parts of the car u should never DIY, a camshaft is not an air-filter.

[shamoo]

It could be valve tap. I just had mine done a few weeks ago. Usually if you don't get better valve springs, it'll happen. After about 2K to 3K miles, go for a valve adjustment.
Oh, and it could be the weather too. Right now, it's cold here, and my motor ticks a little. When it's warmer, it doesn't.
Hope this helps.

alright, i am the one with the cams...

i took it to a shop today...the guy says the cam lobes are hitting the adjusting nut on the rocker arms...but GUDE says nothing of the sort about needing internal upgrades when installing their cams...

cam shafts aren't hard to install if you know what your doing man...and I'm sorry but I'm not paying the $400-$525 I was quoted by shops here...thats a rip...

less mechanically inclined people should not try this, I however do know what I am doing...

so any ideas on what I should do? the shop is trying to grind down the adjusting nuts

a camshaft.. u dont only install them, there is a lot of 'tuneing" involved, especially u got the spockets replaced too..timing, computer remap and shit like those..

[BlackMagic]

well, i am leaving the gears at 0,0 until i get a chance to go to the dyno...and you dont need to remap the ecu with these cams...timing isn't a very hard thing to figure out and adjust...

[SiN-6]

then say good luck to ur bearing and some internal parts..if it was so easy, why will a shop charge u so much?
And i think u do understand, installation of camshaft.. NORMALLY took "at least" 1 full day of work from an experienced mechanic, with proper tuning. you dont just pop it in and say its been installed.

my 272 high-lift cam+spoket took the mechanic 2.5 days to install(well mainly cos of my messy engine bay.)

since you know so much, what kind of tuning is involved with the installation of cams...besides the sprockets and ECU mods...

[court]

honda cams use bearings?
...
hey man, i think my muffler bearing is going bad, think you can help?

take-it-to-the-shop!
camshaft installation from what i know involve timing and adjustment. and from the mechanic who install my camshaft said its not a easy task and the fastest he ever did was 1 full day of work to get it setted. if u done that cam installing within i.e. 5 hr i am guessing ur missing hell a lot of things that need to be done..

before u buy the cam u should consider 'what if' u cant DIY. and need to take it to a shop. boards like this only can help basic installing tips. such as airfilter, muffler, maybe some computer stuff, never something like "how to bolt-on this turbo in my car". for those stuff u better go get it to the shop. and i would guess u still driving that lude and the more u drive, the more damage ur giving to the car, until u got the cam adjusted.

if i know so much i will be a mechanic and not sitting in this boring office waiting for the computers to crash, so i can fix them..ugh..system admin suck..

wrong information!

its including the FconV setting(thats a bitch to do) for my car when installing the 272 cam, it take 3/4 day to get it install into the block..the ECU setting, which takes a lot of time to fine-tune it

i think N/A would be easiler tho

installing cams is an easy job, the only things to be really careful about are not putting crap in the engine and not scratching the bearings, other than that it's pretty straight forward.

typically an aftermarket cam will have more lift, so you need springs made for this or you're going to break things really quick and it can get expensive

[Chris]

yeah remember to install new lifters too whenever you swap cams on those ol crappy pushrods :) Toms right. i dont see how installing a cam is a full day work.

[Spdyjay]

I never did think it was that beneficial to put a cam in a VTEC engine, I probably won't even put one in my non VTEC engine.

open up that valve cover and reinspect that install job, anyone who says that working on a car is hard, is not the person you should be listening too. Anything is easy on a car if you step back, take your time, and work methodically with the proper tools.

Its obvious something is not right, or fitting snug. Their should be little to no play in the valve train. All springs should have retainers. The cam shouldnt woble.

If you cant find anything. Have a friend turn the engine over a few times while you are looking at the valve train.
The problem should present itself.
