I don't use inside building because there air compressor with air hoses.

But I use electric impact for junkyard or remove tires in outside.


$4,000 to do that timing chains. That customer is SMART to have mechanical insurance on it.



another question what exact cause timing chain's sprocket wear out FAST.
history
it 89 F150 with new block 5.0L 302 in 1998 so it have 10,000 miles. We knew it was 10,000 miles how it was clean. But notice timing chain actual too loose for me. Notice Sprocket on camshaft look bad shape.
Oil it was 10w30 with Bastard Junk Fram oil filter.
And preview owner is 19 years old so I bet it been hit 5,000 or 6,000 rpm and never drove on Highway with those miles.

Hey, there is some misunderstand abt the electric impact tools that I mentioned. I'm against the electric impact tools with CORDS, not against the cordless impact tools. My apology. I dont have any cordless impact tools, however they can't use to work on the gas tank like replace fuel pump or gauge sender unit. I use hands or air power tools to work on the gas tanks
hey, you clever abt the cordless impact tool that you harvest the parts in the junkyard.

I think Porsche became popular due to good handling, speed, rear mounted engine, cool factor and possibility a girl magnet. There's a old porsche next to my work with t-top, it's a grey one. It looks like around 1970's.

The answer is James Dean, actor, who loved Porsche and raced for his hobby then he was killed in an auto accident that his Porsche Spider (im not sure the engine in his car, has 4 cams, chain driven in 4H engine) was headon the incoming car. The people from Hollwood or fans of the actor, came to see the Porsche cars at the dealership, asked them what car did the actor killed or he used to driving? The dealer pinpointed the Spyder car as they stared at it, made them crazy as they want to buy this Spyder. That was how the Porsche
became a popular.

Yep!

Here's pic of the Ferrari's flat 12, but there are some other pics used in racing and in other Ferrari models, too. Interesting, I have never heard of H16 before, hmm. I wonder if it uses timing chain or belt in that engine. :hmm:

I witnessed a T-belt in a Ferrari V8, when I smogged it last time. I have notebooks where I recorded for emission inspections on the vehicles. I ll find them then post you later

I dont know the flat 12 use chain or belt or gear driven sprockets. I found the 2006 emission book, states the H12 engines were imported to US on the years of 1987 to 1994. The size of H12 is 4.9L or 301CID.
I smogged some exotic cars at the station abt 4 yrs ago.

Feb.2005 1997 Ferrari F344 GTS, 3.5L V8, M/T, AIR, mileage:27,429

Dec.2004 1997 Ferrari F355 Spider, 3.5L V8, M/T, mileage: 9,030

Apr. 2004 2003 Lamborghini L-147 Murcielago, 6.2L V12,M/T,mileage:2,240

Jan.2004 1997 Ferrari 550 Maranello,5.5L V12,M/T, AIR, mileage:13,333
Failed for MIL
May 2003 1997 Ferrari 456 GTA,5.5L V12, M/T,AIR mileage:10,020
Aborted due to no RPM signal

Some of them were from the nearby exotic dealership.
 
Timing belts are easier to replace while timing chains aren't, IMO. Timing chain last 150k don't they?

Yes, that's what I noticed. Depends on the engine/manufacterer design, really. Some lasts longer than 300k miles, some lot shorter.
 
Still not enough money to get timing belt/water pump serviced, I think I'm gonna start riding bus pretty soon.
