Headgasket project about to launch

[LoneRanger]

anyone had experience with this company? Looks like a really good deal and although the gaskets aren't Toyota, I have never had problems with fel-pro.

Just now getting back to this, believe it or not. I have the new head sitting on the block with the gaskets in place. I am wondering about the position of the camshaft. Does it matter? I am putting it where it was marked on the old one, but the fresh lobes prevent it from dropping snuggly into place. Should I just loosen the valves and bolt the head down and adjust them later. thoughts?

Yes, loosen all the tappets, all the way out. You have to readjust the valves anyway. Check the ends of the adjusters where they hit the valve stems, they can get mushroomed. Can be cleaned up with a grinder, or just get new ones.

Thanks for the reply. Since the valves will have to be adjusted cold the first time, should I just adjust them to spec then redo them after the engine has warmed up?

Ok. I'm stumped. How do you re-attach the timing chain sprocket to the camshaft? when the head is in place, its as if the chain is too short. What am I missing here?

 

[LoneRanger]

Never mind. I figured it out from the shop manual. Put a socket on the crankshaft while pulling up on the timing sprocket and chain, rock back and forth a few times and it goes into place.

heres a helpful PDF on head gaskets. someone should post it at FAQ stickies.

I busted this removing the manifold:
1989 TOYOTA 4RUNNER 2.4L L4 : Electrical-Switch & Relay : Fuel Injection Thermal / Time Switch

Rock auto want $127. for a new one. Any on have on sitting on a used manifold they want to sell:

Well, finally getting back to this project after some months. Life being busy and all.........

I am performing the valve adjusment and trying to be sure I have TDC on cyl 1 compression stroke set properly. I marked the timing chain sprocket at TDC before I took it apart but am now doubting myself. The manual says I must turn the crankshaft 360 deg after adjusting the first set of valves. Does this mean the cam shaft will turn 180 deg?

 

[KLF]

When the engine is at #1 TDC, both intake and exhaust valve rockers on #1 will be loose. You set the lash on the loose rockers. I don't remember which ones will be loose at this point, but it's well documented in the FSM.

When you spin the crank one revolution, the cam only spins 180 deg, so now the other rockers will be loose and you can set those valves.

thanks. just what I was looking for.

I screwed up. Tried cranking today only to discover I had failed to reattatch a fuel line. The result was gas going all over my garage floor. Can someone please tell me where the line coming off the bottom of the thing in the center of the photo attatches too? Its at the end of the injector rail near the firewall.

The thing is the fuel pressure regulator. It attaches to the fuel return line on the firewall with a rubber hose. The hose is rather long, drops down off the regulator, then loops back to the hardline on the firewall.

Thanks. Looking but not seeing an open hard line any where. Do you have a photo perhaps?

It's probably attached at the firewall, but not at the regulator.

 

[LoneRanger]

Yes. Thats it. Just found it. I had it way wrong.

thanks for your help
