V1 Traé’s Goblin (06’ SS/SC #501)

Previous owner "I don't know, l'm not sure" = "NO". Best to replace the suspect parts while they are accessible and you have the dime to spend on peace of mind. Cheap insurance against the need to tear into this at a later date when it may be more difficult to get at - or opt to drop the engine.

I'm not sure either. I wanna say it lines up every second crankshaft turn, but like I said it felt a lot more. Since you're replacing everything it doesn't really matter. Be careful the ecotecs are interference engines. If you do something wrong piston and valves can have contact. But it's pretty simple, their are also good Videos available.

Regarding the direction it: the chain should travel up on the belt tensioner.

Get a new harmonic balancer screw.

The timing marks on the crank and cam sprockets line up in the same place every 2 rotations, but the marks on the chain do not. I don't know the exact number but it is many.

Found something concerning tonight while cleaning.

The top bolt on the front transmission mount was sheared off and it looks like the previous owner attempted to extract the bolt.

it looks very bad and I’m worried the hole can not be repaired. I tried to clean out the hole to see if there were any threads and there are zero. The shoulder of the bolt was jammed into the hole to keep it in place. I had to use a punch on the backside to get the mount off.

does anyone have any ideas? Any help would be greatly appreciated.

Do a Helicoil thread repair, that is strong enough for head bolts.

 

[Rttoys]

Heli coil or time-sert.

I did one inside my engine

Might be enough meat on the transmission to tap the hole out one size larger but that might not work for the mount.

That would be terrifying.

Laminova cores came out very nice. I just cleaned them with degreaser and a soft nylon brush.

I ordered all new gaskets and o-rings for pretty much everything on the engine. I have a head gasket but will not be replacing it at this time. Timing will be done in the next week or two when the kit arrives.

Question for the Laminova cores. I watched a few videos and there is conflicting information as to how the Laminova cores should be clocked in the manifold. I'm not sure if mine have ever been removed but they seemed to be randomly inserted.

Perfect, thank you sir

That would be terrifying.

Not sure where this hole is? But can you use a longer bolt and a nut on the backside?

I was thinking that but I'm not able to put a bolt all the way through to get a nut on it unless it was a smaller size. It is not clear on the backside.

 

[Traé]

So, the tap is not working well, and I don't want to break it off in there. There seems to be bolt left in the hole and I can't get the tap to cut through it and I do not want to drill the hole any larger. It is off center and coming too close to the edge for my comfort.

What are your thoughts on using a type of wedge anchor? once inserted the exposed threads would let me tighten the mount in place and keep it secure.

My only concern would be the force of the anchor expanding and cracking the aluminum.

 

[Ross]

That is a concrete anchor.
How about a few pictures of the issue?
If it was mine, I would be working on extracting the broken bolt.
Have you tried to use a bolt extractor?

Maybe TIG weld onto the broken bolt, maybe a milling machine to center cut the broken bolt.

There is no bolt left to grab onto and no threads left. When I found it the shoulder of the bolt was pressed into the hole that they drilled out. There is currently about a 3/8" hole drilled through the mounting location. I was thinking about that wedge anchor with the understanding it was for concrete to have a way to hold the mount in place.

 

[Gtstorey]

Take it to a machine shop and let them fix it unless that hole can be drilled out and put a bolt all of the way through.

Recent repair on a machine shop youtube channel I folow.

Of course, adding heat to aluminum can help a lot. That looks like most of the bolt is still there so the extractor and heat might take care of it.
