Title: Plug cap/leak question Post by TJ9000 on 03/17/10 at 06:39:19 This may sound dumb but why do you have to TDC if only changing out the plug cap? Hoping to tackle this today so input would be greatly appreciated. |
Title: Re: Plug cap/leak question Post by PipJones on 03/17/10 at 06:47:32 I didn't TDC mine..... it sure does seem like an extra step... why mess with the valve train when all you're doing is removing the head cover.....?????? |

Title: Re: Plug cap/leak question Post by Yonuh Adisi on 03/17/10 at 10:56:34 I think it's probably because once someone tears into the engine that far most of the time they go ahead and do a camchain check. That's just my theory anyway. http://annemccaffreyfans.org/forum/images/smilies/shrug.gif |
Title: Re: Plug cap/leak question Post by verslagen1 on 03/17/10 at 11:18:30 If you're removing the head cover, you want to unload the valves and rockers so it don't snap up on you when you loosen the bolts. |

Title: Re: Plug cap/leak question Post by PipJones on 03/18/10 at 07:03:13 Does the "valve cover" serve as the cam's upper bearing??? cus if not, nothing is being unloaded by TDCing the motor...... .... .... ..... moments later ..... ..... .... I just looked at a parts catalogue and it SURE does look like the valve cover serves at part of the cam bearing..... i.e. I was very lucky to not have someing go wrong when i did my plug leak..... |
