Changing valve springs

I will do this probablly in the coming week and I have just read over shoebox's how to manual. And I was wondering where you got the KD tool and how much did it cost?

NAPA has a similar one usually in stock for a few more dollars might be worth it to not pay shipping and have it in hand sooner.

Re: Changing valve springs

I like the Moroso lever type compressor. It is easy to use and you can reach the back springs with some adjustments of the tool. It also works well with dual springs unlike some. That K-D tool works good for single springs but I found it didn't like to hold onto two springs.

Re: Changing valve springs

I got the kd tool from napa for 30 this morning. I am waiting for my new longtubes to get in so i can do it all at once. I will be installing new springs, locks, retainers, shims, seals, 1.6 roller rockers, and the longtubes. This should really wake my car up.

Re: Changing valve springs

The KD tool will work great. I have a similar tool (not KD) that I have
used to change valve springs three times now. Just be sure each piston
is at TDC and have a magnet to help remove the locks.

Re: Changing valve springs

i bought the KD tool, but i ponied up an extra 10 bucks for the deluxe one with the thick plastic handle that comes off and usees a ratchet if necessary. well worth it for me as my hands got sore after 4 springs and i switched to the ratchet for the remainder.

a quick word of advice on springs: when installing the locks, dab a little petroleum jelly or grease on the insides of the locks so they stick to the valve stem. i found this invaluable with the ones under the cowl as they were hard to seat. you don't wanna be losing anything in that cramped space.

Re: Changing valve springs

I highly recommend the Comp Cams one: http://www.theheadfl.com/pics/camswap24.jpg
The KD tool will tear up your hands and sometimes it can be a pain to get the locks in. The comp cams tool is almost too easy.

Re: Changing valve springs

Yes, I used it once for a spring change and then decided to try something better. I like that Comp thingy. The Moroso is good, too.

Killwhitey, if the pistons are not at TDC you risk dropping the valve into the cylinder.

Re: Changing valve springs

I will start when i get all the parts in. How much time should I prepare for. I think the spring change will be easier because i will have the exhaust off cause i will be doing headers at the same time. How long did it take you guys who have done this??

Re: Changing valve springs

times will vary depending on experience, took me about 4-5 hours (not counting lunch). adjusting valves etc will take additional time.



All times are GMT -5. The time now is 07:42 PM.
