1982 BUICK ELECTRA

Typical onset: 60,000-100,000 mi

Symptoms: White smoke from exhaust, Hard starting when warm, Loss of power, Coolant mixing with oil, Sudden loss of compression

Fix: Oldsmobile 350 diesel suffers head gasket failures, cracked blocks, and premature wear due to weak block castings designed for gas engines. Most require complete engine replacement or rebuild with uprated parts. Figure 20-30 hours labor for R&R plus machine work.

Estimated cost: $3,500-6,500

Typical onset: 80,000-120,000 mi

Symptoms: Transmission fluid in radiator, Coolant in transmission pan, Pink milky fluid on dipstick, Erratic shifting after coolant contamination, Overheating transmission

Fix: The internal cooler in the radiator corrodes through, allowing cross-contamination that destroys the transmission. Requires radiator replacement or external cooler addition, complete transmission flush or rebuild if contamination occurred, and all cooler lines. Emergency repair 8-10 hours, full trans rebuild adds 12-16 hours.

Estimated cost: $800-4,200

Typical onset: 90,000-140,000 mi

Symptoms: No overdrive engagement, Slipping in 4th gear only, Check engine light with code 24 or 28, Harsh 3-4 shift then nothing, Burning smell under highway load

Fix: The 200-4R overdrive section has weak apply pistons and seals that fail, especially behind the 350 V8. Requires transmission removal and rebuild focusing on OD unit with upgraded components. 12-16 hours labor for full rebuild.

Estimated cost: $1,800-2,800

Typical onset: 70,000-110,000 mi

Symptoms: Coolant loss with no visible leak, Rough idle when warm, White smoke at startup, Oil contamination in coolant, Poor fuel economy

Fix: The Buick 231 V6 plastic intake gaskets deteriorate, causing coolant and vacuum leaks. Requires intake removal, gasket set, and often new intake bolts. 4-6 hours labor plus flush if coolant contaminated oil.

Estimated cost: $600-1,000

Typical onset: 60,000-100,000 mi

Symptoms: Clunk when shifting into gear, Excessive vibration at idle in gear, Visible sagging of transmission tail, Harsh engagement from Park

Fix: The rubber transmission mount deteriorates from heat and age, allowing excessive movement. Simple replacement but requires supporting transmission weight. 1-2 hours labor.

Estimated cost: $150-300

Symptoms: Hard starting when hot, Flooding and black smoke, Stalling at idle, Hesitation on acceleration, Fuel smell in garage

Fix: Rochester Quadrajet carburetors develop flooding from worn needle/seats, accelerator pump failures, and vacuum leaks. Most need complete rebuild with ethanol-resistant parts. 3-5 hours for proper rebuild and adjustment.

Estimated cost: $400-750

Symptoms: Intermittent or dead digital gauges, Climate control not responding, Erratic accessory operation, Complete dashboard blackout

Fix: Early digital dashboard and BCM units suffer from cold solder joints and capacitor failures. Requires removal and either professional board repair or replacement with used/rebuilt unit. 2-4 hours R&R, plus electronics repair.

Estimated cost: $300-800
