Sy is dead

[Don W.]

Well my "tick, tick, tick" I wrote about in an earlier thread turned into a knock-knock-knock. That tick had been there for a long time so I'm surprised it went to this so fast. (was thinkin' it might have been a lifter.) Will be looking at a rebuild. Haven't even cut the filter yet. Sounds like a rod but could be a main I suppose. When I crank it I don't hear any weak cyls so don't think it's a piston. But ya never know until it's apart.

Garage way to small for a project like this but I've got a couple of angles to check out there. Need to work out a parts list and some costs then "apply for funding" as my wife put it. :rotf:

Prolly be a few weeks before I actually start so feel free to post. I'll be looking for parts lists and costs, checking into machining, build ideas. Subject to change but thinking nothing fancy as-far-as high HP is concerned just a solid rebuild with good parts. Main idea, since it'll be apart, will be converting to Vortec heads.

To be continued...

Bummer to here the engines dead but now there is room to make more power

Re: Sy is dead

Are you at least doing 4 bolt mains and a treated stock crank ? With the vortecs your going to want bigger inj and some new calibrations on the ultimate unless you already did . I dont see it in the sig .


Have fun either way , thats all that matters .Go more than you need on the build and its fun level declines . Good luck and hope the damage is minimal .

Keep in mind it will not be pass EGR function test if you switch to Vortec heads.

Re: Sy is dead

Sorry to hear that Don... I've always followed your ticking cuz mine has a tick too, but mine is definitely the injectors feeding back up through the AFPR.... any warning signs before it went Knock knock??

Don't know if "fun" is right word. But I haven't done a rebuild in a long time so I'm actually looking forward to that part. As far as what actually goes into the build that's all to be determined. But it's suggestions like yours that help.

Already figured I'll be going to code 59 or a custom chip of some kind since I'll prolly switch to 50#ers.

Thanks,

Just that it didn't want to pull above about 3500. Seemed to bog there. Motor definitely was not happy at that point. DM showed a huge amount of knock but I'm not sure if it was real or things going away in the bottom end.

That's a typo... you meant 60#ers.

Not to hijack, but i have vortecs on my build. It passed smog, but i keep getting code 32 (egr system). What can to fix the code?

You only passed because the tech did not test EGR function or didn't know what he was doing.

Re: Sy is dead

Hey Don really sorry to hear that!! But on the bright side I'm already looking forward to hearing about your Vortec build.

Re: Sy is dead

if you apply for funds and don't get as much as you need just do the whole vortec motor swap, pull a late model vortec motor, mod the intake and heads and you're good to go. you get the vortec heads, better rods and a bigger cam in one shot.

Yea, thats what i was thinking. The truck looks visually stock.

Re: Sy is dead

Like I may have mentioned; step one is find a location to work on it. Then get started, pull the motor, see what happened, and at least get a pic up. Looks like allot of $$ but the the basic build (no core) from RPM looks interesting and would get me back on road quickly. (No offence to anyone else here please, I just haven't looked anywhere else yet.)

SMOG shouldn't be an issue as I've already moved the registered location of the truck to where SMOG isn't required.

Re: Sy is dead

Awh man I hope my ticking does not turn into that. I have had mine ticking/knocking for 3 years. Its still going strong. Goes away when everything heats up.

Re: Sy is dead

I am having the same ticking. I put lucas oil in and it went away but I plan on pulling my motorout before it gets trashed. Good luck Don.

Re: Sy is dead

If you're interested, I'll find the PN for the short block ass'y I used, and you can check on current price and availability.

Good info. If you you have the time sure, I'll take the number. Don't have it apart yet but all info is appreciated.

The plan is to have the Sy in pieces next week but don't hold yur breath.:roll: A) Never pulled a Sy motor before, B) I tend to be slow anyway.:rotf:

Thanks.

Re: Sy is dead

Sorry to hear about the motor

. At least you got to turn some good numbers before she went

! I found out this past weekend that I am in the same boat as you, only have 60 psi of compression in #1 (other 5 are between 150 to 175 psi) so my engine is done too... At least I we will be able to get our sy/ty engine "stripe" eh

? Got my transmission one years ago, twice. I'm gonna go Vortec myself so please keep us updated on your build. Hope to have mine back together in one or two years...
